Description
The invention relates to and utilize weld seam welding mode that the corrosion resistant metal coating is engaged in Fe system or Cu is the lining material that substrate metal forms.
In the past, be the method for substrate metal about corrosion resistant metal coatings such as Ti or Zr being engaged in Fe system or Cu, existing following the whole bag of tricks is implemented or proposes.Also promptly: outburst crimping method, the corrosion resistant metal plate is superimposed in the surface of substrate metal plate, utilize configuration gunpowder explosive force thereon with both in addition crimping; Rolling process is utilized the rolling process roller, and the substrate metal plate and the corrosion resistant metal plate of mutual lamination prolonged pressure, and both are engaged; Utilize methods such as spot welding welding in addition.
In above-mentioned various existing methods, still have following point.
(1) by outburst crimping method, because along with the outburst of gunpowder can produce noise, so most situation can be subjected to implementing the restriction in place.And lining material size or the shape that can make also are subject to many limitations, and manufacturing cost is also higher, and this is its shortcoming.And this method is not suitable for the manufacturing of lamellar lining material, wishes to get the lamellar lining material of this kind, must impose calendering etc. again after slab is broken out crimping, causes the construction procedure number to increase, and this is its difficulty.
(2) by rolling process, except can make lining material be subject to tabular owing to need extensive rolling equipment, so cost of equipment increases, this is its shortcoming.And, owing to can't impose lining etc. at substrate metal with curved surface, thus being short of accommodation for the substrate metal shape, this is its difficulty.And, only rely on calendering, if compare, the hypodynamic situation of joint is often arranged with outburst crimping etc., also often need after calendering, impose diffusion heat treatments, construction procedure number and cost easily increase, and this also is its difficulty.
(3) if by the method that adopts the spot welding welding, then owing to the spot welding weld portion that must form many diffusing point-like, so engage quite bothersome.And because of being a joint, the sealing between often engaging force deficiency, and substrate metal and corrosion resistant metal lining is difficult to reach, and this is its difficulty.
The object of the present invention is to provide and a kind ofly utilize the weld seam welding to make simply, and the superior lining material of bond strength.
By a kind of lining material that the present invention proposes, it is characterized by by following mode and constitute.Be the substrate metal layer promptly also at the Fe that constitutes by Fe or Fe alloy, have Ni be the metal level lamination thereon, and from this Fe be that to have wire netting to be stacked on this Ni be metal level to the metal level opposition side.And, with Ni be the metal level opposition side, have the corrosion resistant metal coating to be contacted with this wire netting and dispose, these Fe are that substrate metal layer, Ni are that metal level, wire netting and corrosion resistant metal coating are to utilize by roller electrode to form wire or planar weld seam weld portion and in addition combination.The corrosion resistant metal coating is by being constituted with a certain metal or stainless steel by principal component among Ti, Zr, Nb, Ta, the Ni.Whereby, just can make corrosion resistant metal coating and the substrate metal layer strong lining material that combines in addition.And Fe is that the substrate metal layer can be made of for example carbon steel, stainless steel and other steel alloys.
The lining material of above-mentioned formation, be on the substrate metal layer, by Ni is the order lamination in addition of metal level, wire netting, corrosion resistant metal coating, at its stack direction, utilize roller electrode to exert pressure and make the laminated body heating that has a resistance, more under this state, roller electrode is rotated with respect to laminated body by energising, form the weld seam weld portion, mode promptly can be made into lining material whereby.In this occasion, laminated body can be clipped between many roller electrodes and be switched on.On the other hand, also can adopt so-called continuous weld burning-on method etc., also promptly utilize roller electrode, do not clamp laminated body and implement the method for weld seam welding, for example at corrosion resistant metal coating side configuration roller electrode, therewith accordingly, another roller electrode is configured in the same side, and form that to connect corrosion resistant metal coating, wire netting and Ni at least from roller electrode side on one side be metal level, after turning along its stromatolith towards transverse direction, penetrate each layer with above-mentioned reverse order again, and, weld to implement towards the energising path that another side roller electrode side passes.And electrical current can adopt any of alternating current or DC current.
Wire netting is owing to be formed with mesh, so the sectional area of switching on is little, and because of the Ni of adjacency is that the contact area of metal level and corrosion resistant metal coating is also little, so resistance heating is especially big nearby.And, become the wire netting of high temperature, exert pressure by roller electrode, and invade because of softening corrosion resistant metal coating of above-mentioned heating and at least one side in the substrate metal layer, because this intrusion effect or because of engaging the increase of extending area etc. due to wire netting concavo-convex, thereby can improve the adhesion of corrosion resistant metal coating and substrate metal interlayer, this is presumable by people.
And people can infer that Ni is that metal level has at least a in the following function.
(1) owing to resistance heating, the part of itself fusing at least, perhaps the part with substrate metal layer or wire netting together melts, and so as to producing liquid phase, this liquid phase is supplied to the contact site of wire netting and substrate metal layer.Ni and alloy thereof because and the wetting quality that constitutes between the Fe based material of substrate metal layer good, so the effect of welding material takes place the liquid phase that is produced, thereby have the function of raising wire netting and substrate metal interlayer adhesion.And the liquid phase that is produced also is supplied to the mesh of wire netting, also may reach corrosion resistant metal coating and substrate metal layer sometimes at this mesh, or the welding material function that the corrosion resistant metal coating is engaged with wire netting.
(2) even suppose in the situation that does not produce liquid phase, also because resistance heating, at least the part of its composition can be towards wire netting and substrate metal layer, so through mesh towards the diffusion-alloying of corrosion resistant metal coating, produce the adhesion effect that improves between these parts whereby.
About Ni is metal level, owing to can produce flowability and the superior liquid phase of wetting quality by resistance heating, so applicable to comprising Ni alloy at least a among Cr, B, Si, C, P, Mo, W, the Fe, especially be the alloy of the Fe of the Si of B, 3.5-5.5 weight % of principal component and the Cr that contains 5-16 weight %, 2-4 weight % and 2-5 weight % with Ni.
So, be the effect of metal level by above-mentioned wire netting and Ni, just can make corrosion resistant metal coating and the base material gold layer lining material of strong be combined in addition.Be the welding effect or the diffusion bond effect of metal level particularly by utilizing Ni, with not using Ni is that metal level and the situation of making lining material are compared, plus-pressure or welding current in the time of can be with the weld seam welding lower, even event is in the sizable situation of thickness of for example substrate metal layer and corrosion resistant metal coating, also can be by less plus-pressure or welding current, and obtain better engagement state.
At this, if wire netting be with near fusion temp than the corrosion resistant metal coating more the material of hard constitute, then because of the intrusion effect of above-mentioned wire netting to corrosion resistant metal coating side strengthens, so bond strength more can be improved.And, by adjusting the caloric value that wire netting is in contact with it portion, so that utilize this heating to make the corrosion resistant metal coating moderately softening, can promote the intrusion of wire netting towards the corrosion resistant metal coating, make the adhesion between wire netting and corrosion resistant metal coating more strong.And, by wire netting and corrosion resistant metal coating are constituted with the material that compatibility is superior each other, can improve bond strength between the two.To this situation, so-called " compatibility is superior " is meant that for example near the mutual diffusivity junction temperature is superior, or superior with the wetting quality of the part fusing liquid phase that produces in these.
About concrete example, can adopt by the Fe based material is that main body constitutes wire netting, and by so that any is the combination that the metal of principal component constitutes the corrosion resistant metal coating among Ti or the Zr, as an example.In this occasion, engage aspect effect and the wire netting intrusion effect etc. two producing because of two-layer phase counterdiffusion, all can obtain good result.About constituting the Fe based material of wire netting, various stainless steels (for example SUS304 alloy etc.) are owing to be difficult for getting rusty at net surface, and have higher ratio resistance, and heat generation is superior during energising, so be suitable for use.
About the material of wire netting,, also can use so that any is principal component among Ni, the Cu except that Fe.This kind wire netting is applicable to that the corrosion resistant metal coating is by so that any is the metal of principal component among Nb, Ta, the Ni, or the occasion that stainless steel constituted.The wire netting of these materials because the one partial melting is produced when the weld seam welding liquid phase, and the corrosion resistant metal coating of above-mentioned material between wetting quality aspect comparatively superior, so, can reach good zygosity by a kind of welding effect.
Ni is that metal level can include with Ni is the metal forming of principal component.The heat conductivity of metal forming is good, can make its function as a kind of heat sink that dissipates from weld seam weld portion heating, has to prevent that in the composition surface of the corrosion resistant metal coating weld seam welding part that do not end from the effect of oxidation taking place.On the other hand, Ni is that metal level also can be the coating that is formed on the substrate metal layer.Coating can utilize various gas phase system embrane methods such as plating, electroless coating even evaporation, spraying to form.And Ni is that metal level can be the metal powder layer of principal component in order to Ni also.About the formation method of this powder bed, can list metal dust is mixed together into pasty state with scaling powder, be coated in the method on the substrate metal layer.In addition, also can being sprayed on the substrate metal layer metal dust is molten, is metal level to form Ni.
Secondly, in the occasion that forms wire netting with single material, this wire netting can be all to be the metallic plate of the joint-cutting of stagger mode arrangement along many that the thickness of slab direction connects, to forming the direction distortion that direction intersects with this joint-cutting, and make these joint-cuttings to the direction opening of this distortion and form mesh wire netting (below, in this manual, claim this kind wire netting to be " laths of metal net ").The laths of metal net can be by being constituted with any metal by principal component among Fe, Ni, the Cu.This kind laths of metal net is easy to manufacture, can reduce the manufacturing cost of lining material effectively.The laths of metal net more particularly, can adopt with the two side portions of metallic plate with respect to each joint-cutting formation direction, towards being out of shape along the thickness of slab direction of this metallic plate direction opposite each other, so that joint-cutting forms opening.And, also can use to form joint-cutting and make its opening and the laths of metal net impose the product that calendering forms.
In addition, wire netting also can be with same kind or different kinds of metals net in addition behind the multi-disc lamination and used.
In above-mentioned lining material, though be with and be the mode of metal level with wire netting and Ni, implement engaging of corrosion resistant metal coating and substrate metal layer, but only by Jie of wire netting in the occasion that can guarantee abundant engaging force, also can adopt not contain the formation that Ni is a metal level.For example, can following formation come example, also be, will be by being that the formed wire netting of principal component metal is stacked on the substrate metal layer that is made of Fe or Fe alloy with Fe, more at the opposition side of this wire netting and substrate metal layer, contact with this wire netting and to dispose the corrosion resistant metal coating, and utilize by roller electrode and form wire or planar weld seam weld portion these substrate metal layers, wire netting and corrosion resistant metal coating constituting of combination in addition.In this occasion, the corrosion resistant metal coating is by being constituted with any metal or stainless steel by principal component among Ti, Zr, Nb, Ta, the Ni.Whereby, just can obtain the strong lining material that is combined into of corrosion resistant metal coating and substrate metal layer.And the substrate metal layer can be made of for example carbon steel, stainless steel and other steel alloys.
And another example can be enumerated following situation, also is that the corrosion resistant metal coating is made of any metal or stainless steel by principal component among Ti, Zr, Nb, Ta, the Ni; And the part of wire netting is by the metal by principal component is constituted with Fe, or its whole or part is by being constituted with any metal by principal component among Ni, the Cu.In addition, in the occasion that forms wire netting by the metal that with Cu is principal component, also can constitute by containing Cu alloy at least a among Zn, Sn, Ni, the P.Specifically, can constitute by containing the alloy of Sn in 1-20 weight % scope.More particularly, can constitute by containing the alloy of P below 0.5 weight % again.
About by the concrete situation that constitutes wire netting part situation with Fe for the principal component metal, can following situation come example.Also promptly, can use with Fe, in addition the multi-ply construction net that forms of multi-disc lamination as the wire netting of principal component material with the wire netting of the metal beyond the Fe as the principal component material.For example, can use in corrosion resistant metal coating side and be configured to the wire netting of Fe as the principal component material, and be that substrate metal layer side is configured to two layers of structure net that Ni or Cu are the wire netting of principal component material, or use between and be configured to the three-layer structure net of Cu as the wire netting of principal component material with two wire nettings of Fe as the principal component material at Fe.
Secondly, be another example that metal level constitutes about not containing Ni, can following situation come example.Also promptly, the corrosion resistant metal coating is made of any metal or stainless steel by principal component among Ti, Zr, Nb, Ta, the Ni; And wire netting is so that any is the laths of metal net that the principal component metal is constituted among Fe, Ni, the Cu by integral body.By the use of laths of metal net, can save the manufacturing cost of lining material.
Secondly, a kind of lining material by the present invention proposes is characterized by as following formation.Also promptly, will be worked out by the metal wire rod more than two kinds of material inequality and be formed wire netting, be stacked on the substrate metal layer that is constituted by Fe or Fe alloy or Cu or Cu alloy.And, at this wire netting opposition side, contact with this wire netting and dispose the corrosion resistant metal coating.These substrate metal layers, wire netting and corrosion resistant metal coating are to utilize by roller electrode to form the in addition combination of wire or planar weld seam weld portion.
Have the wire netting of metal wire rod more than two kinds owing to use, thereby can obtain for example following effect.
(1), can adjust the resistance value of wire netting integral body by this material combination by the mode that will be made up than the metal wire rod of resistance inequality material.For example, if adopt single material, contingent situation is: than too high in resistance and the quantitative change of generating heat is big, wire netting can melt or disperse; Perhaps corrosion resistant metal coating or substrate metal layer are overbated, and wire netting is embedded in one of them, and the corrosion resistant metal coating of dependence wire netting intrusion and the adhesion of substrate metal layer are reduced.Therefore, if, adjust it, then can avoid above-mentioned phenomenon, and can reach the good binding state than resistance by using various material to constitute the mode of wire netting.
(2) in the occasion that for example constitutes wire netting with two kinds of metal wire rods, if one of them is to constitute for corrosion resistant metal coating compatibility or the higher material of invasive, and another is to constitute for substrate metal layer compatibility or the higher material of invasive, then can improve bond strength between the two.
To this, also configurable intermediate metal layer between substrate metal layer and wire netting.In this occasion, can be by the material of substrate metal layer and wire netting suitable selected of the material of metal level in the middle of it, for example in the occasion of using the substrate metal layer (is the substrate metal layer hereinafter referred to as Fe) that is made of Fe or Fe alloy, can use Ni system or Cu is metal level.In this occasion, be the formation situation and the effect of metal level about Ni system or Cu because and the Ni of a kind of lining material of proposing of foremost of the present invention be that metal level is roughly the same, so its explanation omission.And the back is suitable for material and the effect that Cu is the intermediate metal layer of substrate metal layer with explanation.
In addition, in the above-described configuration, the corrosion resistant metal coating, specifically, can be by so that any is that the metal or the stainless steel of principal component constitutes among Ti, Zr, Nb, Ta, the Ni.And wire netting specifically, can comprise: first group of wire rod, by along set direction each other many metal wire rods of almost parallel assortment constituted; And second group of wire rod, by along the direction almost parallel assortment each other that intersects with above-mentioned wire rod, and many metal wire rods of material and this first group of wire rod inequality constitute.
And, be the occasion of substrate metal layer using Fe, specifically, in this first and second group wire rod at least one group can be by being constituted with any metal among Fe, Ni, the Cu by principal component.More particularly, first group of wire rod can be made of stainless steel, and second group of wire rod can be by constituting than first group of wire rod material littler than resistance.In this occasion, second group of wire rod can be by so that any is that the metal of principal component constitutes among Fe, Ni, the Cu.The one example is: can constitute second group of wire rod by carbon steel wire rod.And, also can utilize zinc etc. to impose corrosion protection covering on the carbon steel wire rod surface.
On the other hand, in the occasion of using the substrate metal layer (is the substrate metal layer hereinafter referred to as Cu) that constitutes by Cu or Cu alloy, specifically, can be by following formation.Also promptly, being that to be stacked on Cu be on the substrate metal layer to substrate metal layer intermediate metal layer that low-melting metal is constituted than Cu.And, be substrate metal layer opposition side with Cu certainly, wire netting is stacked on this intermediate metal layer.This wire netting has: first group of wire rod, by along set direction each other many metal wire rods of almost parallel assortment constituted; And second group of wire rod, by along the direction almost parallel assortment each other that intersects with above-mentioned wire rod, and many metal wire rods of material and this first group of wire rod inequality constitute; This first and second the group wire rod at least one group can be by being constituted with any metal among Fe, Ni, the Cu by principal component.And, from having the corrosion resistant metal coating to be stacked on this wire netting with this intermediate metal layer opposition side, and these substrate metal layers, intermediate metal layer, wire netting and corrosion resistant metal coating are to be formed wire by roller electrode or planar weld seam weld portion is interosculated.
Using Cu is in the formation of substrate metal layer, combination about two kinds of wire rods constituting wire netting, specifically, one group is to constitute to have high-affinity or invasive material for the corrosion resistant metal coating in first group and the second group of wire rod, and another group is to be the material formation that the substrate metal layer has high-affinity, can to improve bond strength between the two thus for Cu.To this, in material for substrate metal layer tool high-affinity, should select with by the intermediate metal layer fusing good material of liquid phase wetting quality that produces.And, about the material of this intermediate metal layer, should select Cu substrate metal layer and all good material of above-mentioned wire netting two side's wetting qualities.
So the material of selected each layer of mode and wire netting can be reached following effect.Also promptly, wire netting is because of being formed with mesh, so the energising sectional area is little, so near resistance heating change wire netting is big.And, exert pressure by roller electrode, wire netting is invaded towards corrosion resistant metal coating side at least, and the one partial melting produces liquid phase to intermediate metal layer because of this generates heat at least, the effect of welding material takes place in this liquid phase, make wire netting mutually deposited with the substrate metal layer, mode just forms the lining material that is combined in the substrate metal layer with the corrosion resistant metal coating strongly whereby.This liquid phase also can be passed the mesh of wire netting sometimes, detour to the contact side of this corrosion resistant metal coating, thereby help the improvement of bond strength.
In addition, be in the formation of substrate metal layer using Cu, intermediate metal layer should use fusing point below 1000 ℃, is more preferred from the material below 950 ℃, so that the heating when being accompanied by the weld seam welding and produce the liquid phase of capacity.On the other hand, if the use fusing point is the alloy below 70 ℃, then use the environment temperature of lining material only to rise a little, intermediate metal layer is promptly softening, the bond strength of substrate metal layer and wire netting can reduce hastily, so should use fusing point higher, preferably use fusing point at the alloy more than 100 ℃.
Above-mentioned intermediate metal layer specifically, can adopt Cu or the good metal or alloy of Cu alloy wetting quality, for example contains that at least a above material of 50 weight % that is aggregated in constitutes among Pb, Sn, the Zn.Wherein, be that basic alloy (for example various slicken solder class) can be fit to use especially with Pb-Sn.To constitute intermediate metal layer as above-mentioned alloy, can improve the weldability that wire netting and Cu are the substrate metal interlayer, can obtain the more superior lining material of bond strength.About on the substrate metal layer, forming method as above-mentioned intermediate metal layer, except the method that use to constitute the metal or alloy paillon foil, adoptable have the fusion galvanoplastic or alloy powder stirred into pasty state with scaling powder etc. and be coated on method on the substrate metal laminar surface etc.And, for the fusing point of adjusting intermediate metal layer or increase intensity, can in above-mentioned alloy, add among In, Ga, Zn, Ag, the Cu more than one.
On the other hand, at above-mentioned alloy in addition, the constituent material that following substances can be used as intermediate metal layer is used.
(1) contains Ag and Cu and add up to the above material of 50 weight %.
(2) contain Cu more than 70 weight %, the material of P more than 3 weight %.
To using Cu is in the formation of substrate metal layer, at the corrosion resistant metal coating is that any is the occasion that the principal component metal is constituted in Ti and Zr, one group that constitutes in the wire netting wire rod group can be made of stainless steel, and another group can be made of the metal that with Cu is principal component.By mode as constituted above, the corrosion resistant metal coating is moderately softening because of the heating of wire netting, can promote the intrusion effect of STAINLESS STEEL WIRE portion, improves engaging force.
On the other hand, at the corrosion resistant metal coating is that any is the occasion that principal component metal or stainless steel are constituted in Nb, Ta, Ni, if one group that constitutes in the wire netting wire rod group is by the metal by principal component is constituted with Ni, and another group is by the metal by principal component is constituted with Cu, then has effect.In this occasion, be the wire rod group of principal component with Ni, when the weld seam welding, one partial melting and produce liquid phase can make the engaging force between corrosion resistant metal coating and wire netting increase by the welding effect that this liquid phase produced.
Secondly, the another kind of lining material that the present invention proposes is about having the not lining material of containing metal net formation.Also promptly, by the material of corrosion resistant metal coating,, be that metal level also can form the good weld seam weld portion of bond strength only with Ni system or Cu even do not use wire netting.This lining material is characterized by and comprises: Fe is the substrate metal layer; Ni system or Cu are metal level, and being stacked on this Fe is the substrate metal layer; The corrosion resistant metal coating, oneself and this Fe are that substrate metal layer opposition side is stacked on this Ni or Cu is a metal level, and by being constituted with any metal or stainless steel by principal component among Nb, Ta, Ni, the Zr; And the weld seam weld portion that each layer mutually combined.In this occasion, with the Ni in the lining material that foremost of the present invention proposes is that metal level is the same, and its Ni is that metal level and Cu are metal level in this lining material, and can be with Ni or Cu is the metal forming of principal component, or be formed at electrodeposited coating on the substrate metal layer, or be powder bed or meltblown layer.
In the above-described configuration, for example to serve as reasons with Ni be the occasion that principal component metal or stainless steel constitute to the corrosion resistant metal coating, can reach good bond strength especially.For example, if the corrosion resistant metal coating is by being principal component with Ni, and contains the Ni alloy of the Mo of the Fe of the Cr of 13-35 weight % and 3-25 weight % and 3-35 weight %; Or by being principal component with Ni, and contain the formations such as Ni alloy of the Fe of the Cr of 13-30 weight % and 3-35 weight %, can obtain the superior especially lining material of chemical proof and high temperature corrosion resistance.
Using Ni is the occasion of metal level, and can containing Ni alloy at least a among Cr, B, Si, C, P, Mo, W, the Fe, to constitute this Ni be metal level.Can Ni be principal component particularly, and the alloy that contains the Fe of the Si of B, 3.5-5.5 weight % of Cr, 2-4 weight % of 5-16 weight % and 2-5 weight % constitute.The Ni that constitutes with this alloy is a metal level, produces flowability and all good liquid phase of wetting quality owing to melting when the resistance heating, so can obtain the superior lining material of bond strength.
On the other hand, be the occasion of metal level using Cu, by to contain the mode that at least a Cu alloy constitutes among Zn, Sn, Ni, the P, can obtain the superior lining material of bond strength.In this occasion, Cu is that metal level can be made of Cu alloy described as follows specifically.
(1) contains the alloy (for example brass etc.) of Zn in 20-50 weight % scope.
(2) contain Zn at 3-30 weight %, the Ni alloy (for example nickeline etc.) in 5-40 weight % (but the total amount of Zn and Ni is no more than 50 weight %) scope
In the various lining materials of the present invention discussed above, has Fe and is the substrate metal layer, in for example following machine or structure.

Also namely, roller electrode 6 is configured in corrosion resistant metal sheet material 4 sides, and correspondingly another roller electrode 6 is disposed at the same side. To these roller electrode 6 energisings, then form from roller electrode 6 sides on one side and connected at least corrosion resistant metal sheet material 4, wire netting 3 and Ni paper tinsel 2, after changing along its stromatolith towards transverse direction, penetrate each layer with above-mentioned reverse order once again, and towards the energising path I that roller electrode 6 sides of another side pass, so form the weld seam weld portion.
Fig. 3 and Fig. 4 represent the supposition profile construction schematic diagram (Fig. 3 is the B-B section, and Fig. 4 is the A-A section) of lining material 10 shown in Figure 2. Wire netting 3 is owing to be formed with mesh, so the contact area (sectional area of also namely switching on) of 4 of the Ni paper tinsel 2 of adjacency and corrosion resistant metal sheet materials is less, so resistance heating is large especially in its vicinity. It is believed that, because this heating, be that easily the softening corrosion resistant metal sheet material 4 that is made of Ti or Zr etc. is just moderately softening for substrate metal layer 1 than Fe, because the plus-pressure of roller electrode 6, wire netting 3 is invaded darker towards this softening corrosion resistant metal sheet material 4, both just form each other strongly combination.
On the other hand, Ni paper tinsel 2 is owing to its resistance heating, and the part of itself melts at least, and perhaps the part with substrate metal layer 1 or wire netting 3 melts simultaneously, and so as to producing liquid phase, this liquid phase mainly is the contact site that is supplied to wire netting 3 and substrate metal layer 1. And, consist of the Ni of Ni paper tinsel 2 and since its with the Fe based material that consists of substrate metal layer 1 between wetting quality or diffusivity is good mutually, so have the effect that improves wire netting 3 and substrate metal layer 1 adhesion, this is that people infer.
As above-mentioned, as shown in Figure 3, it is believed that because the intrusion effect of wire netting 3 and utilize the welding of Ni paper tinsel 2 or the synergism of composition diffusion effect, corrosion resistant metal sheet material 4 just with the 1 strong ground combination of substrate metal layer. And, in the intrusion section of 4 of wire netting 3 and corrosion resistant metal sheet materials, sometimes also may form diffusion layer 3a along with between the two composition diffusion.
In addition, as shown in Figure 4, be not formed with the part of weld seam weld portion 8 in laminated body 5, be not created in the combination between each layer 1-4. To this, the corrosion resistant metal sheet material 4 in lining material 10 integral body and the adhesion of substrate metal layer 1 can be done suitable adjustment by the formation number that changes weld seam weld portion 8, formation interval and formation width. And the width of weld seam weld portion 8 can adjust by the width that changes roller electrode 6. And, particularly in the occasion of the wider weld seam weld portion 8 of needs (perhaps planar weld seam weld portion), as long as make the weld seam weld portion 8 of adjacency join or overlap.
Secondly, the material of corrosion resistant metal sheet material 4 and thickness can be decided by the environment that uses lining material. The distance of the thickness of wire netting 3 (forming the wire rod wire diameter of wire netting) and mesh, and Ni is material and the thickness of metal level, can be suitably selected by the material of corrosion resistant metal sheet material 4 and thickness, so as and substrate metal layer 1 between obtain best engaging force. So, in case determined material and the size of each layer 1-4, can be corresponding with it and suitably set out the condition of weld seam welding, also be plus-pressure, welding speed (such as the velocity of rotation of roller electrode 6), conduction time, stop time of welding current value, roller electrode 6 etc. For example, the value of welding current can be very big at resistance heating, causes wire netting 3 to melt; Or in contrast, it is too small to generate heat, and the engagement state that causes each layer is because being adjusted in the scope that does not melt the situation such as insufficient. And, the plus-pressure of being executed by roller electrode 6 can not produce too much or do not produce deficiency towards being pressed into of corrosion resistant metal sheet material 4 (or substrate metal layer 1) at wire netting 3, and extreme the intrusion to the scope on laminated body 5 surfaces that roller electrode 6 do not occur adjusted.
For example, use stainless (steel) wire 3 and Ni paper tinsel 2, the occasion that the corrosion resistant metal sheet material 4 of Ti or Zr system is engaged with the substrate metal layer 1 of carbon steel is if the thickness of corrosion resistant metal sheet material 4 is T, the wire diameter of wire netting 3 is M, and then the value of M/T can be set in the scope of 0.1-0.4. If M/T is less than 0.1, then the intrusion of 3 pairs of corrosion resistant metal sheet materials 4 of wire netting is not enough, and bond strength just reduces. And, if surpass 0.4, then instead intrusion becomes excessive, cause the mesh emersion of wire netting 3 to the surface of corrosion resistant metal sheet material 4, cause bad order, or the part of wire netting 3 passes the face side of corrosion resistant metal sheet material 4, the situation such as break, also may thereby impairment to the corrosion protection result of substrate metal layer 1. The value of M/T is advisable with 0.15-0.30.
On the other hand, (in abutting connection with the inboard of wire rod to each other, also being the interval in space) is the occasion of D at the interval that makes mesh, and D/M should be set in the scope of 1-10. If D/M is less than 1, then mesh spaces is too small, and the depth of invasion of wire netting 3 is not enough, and bond strength reduces, because the liquid phase that the fusing of Ni paper tinsel 2 produces is difficult to soak into mesh, can't fully reach across corrosion resistant metal sheet material 4 and the welding effect of substrate metal layer 1 of wire netting 3 mesh. On the other hand, in case D/M surpasses 10, then invade to become to the interval of wire netting 3 wire rods of corrosion resistant metal sheet material 4 and dredge, cause the reduction that engages effect. The value of D/M should be decided to be 1.5-7.
Secondly, only with wire netting 3, or only with Ni be metal level or Cu be the metal level lamination between corrosion resistant metal sheet material 4 and substrate metal layer 1, and consist of the occasion of lining material 10, the formation of weld seam weld portion 8 is also by implementing with principle same shown in Fig. 1. And in the formation of the wire netting 3 that uses stainless steel for example and the corrosion resistant metal sheet material 4 of Ti or Zr system, this seam weld portion 8 can be speculated as form as shown in Figure 5. Also namely, it is believed that wire netting 3 is to invade dearly and be fixed in corrosion resistant metal sheet material 4 sides, and with the contact site of substrate metal layer 1 heating because energising institute has a resistance and forming component diffusion layer 13, wire netting 3 is just combined with substrate metal layer 1. And in the mesh of wire netting 3, the part that sometimes directly contacts at corrosion resistant metal sheet material 4 and substrate metal layer 1 also produces some composition diffusion layers 11. In addition, the intrusion section periphery at 3 pairs of corrosion resistant metal sheet materials 4 of wire netting also may produce composition diffusion layer 12. And, to mesh spaces D, the wire diameter M of this occasion wire netting 3 and the value of corrosion resistant metal sheet material 4 thickness T, preferably with satisfy with and be that the aforementioned lining material of metal level consists of same condition and set with Ni.
On the other hand, in the occasion of not using wire netting 3, for example use Ni paper tinsel 2 as metal level, and use the Nb thin plate as the occasion of corrosion resistant metal sheet material 4, people infer that its weld seam weld portion 8 is into structure as shown in Figure 6. Also be, it is believed that the contact site on 1 on Ni paper tinsel 2 and corrosion resistant metal sheet material 4 and substrate metal layer, heating has a resistance, make 2 fusings of Ni paper tinsel, and the composition diffusion occurs between generation liquid phase and corrosion resistant metal sheet material 4 and substrate metal layer 1, thereby form diffusion layer 14 and 15, corrosion resistant metal sheet material 4 just is engaged with substrate metal layer 1.
Secondly, using wire netting 3, occasion so that the corrosion resistant metal sheet material 4 that thickness is especially big is engaged with substrate metal layer 1 for guaranteeing the necessary current density of weld seam welding, just must cooperate the thickness of corrosion resistant metal sheet material 4 to improve welding current or lengthen conduction time. Yet, wire netting 3 because and the contact area of corrosion resistant metal sheet material 4 little, higher than resistance, so along with the increase of welding current, near the heating that wire netting 3, easily produces surplus. Its result, just such shown in Fig. 7 a, corrosion resistant metal sheet material 4 is just overbated, and wire netting 3 buries fully in corrosion resistant metal sheet material 4, the joint effect that detracts sometimes and produce because of wire netting 3 intrusions. In this occasion, as shown in Fig. 7 b, overlap two or more wire netting 3 if use, even occur as the above-mentioned situation that buries, by the part of this multi-disc wire netting 3 across between substrate metal layer 1 and the corrosion resistant metal sheet material 4 and the fact that exists also can be guaranteed certain adhesion.
On the other hand, also can be as shown in Fig. 7 c, with the wire netting 3a of 2 material inequalities and 3b in addition lamination use. The one example is the occasion that consists of corrosion resistant metal sheet material 4 with Ti or Zr based material, if at the net of corrosion resistant metal sheet material 4 sides configuration for the better material of corrosion resistant metal sheet material 4 invasives, for example 3a (for example stainless (steel) wire) nets in Fe system; And disposing this net 3a of Fe system and Fe in substrate metal layer 1 side is the net of any equal tool high-affinity material of substrate metal layer 1, for example 3b (for example Ni wire netting) nets in Ni system, and when forming the weld seam weld portion, then to be incorporated into Fe between two parties with the net 3b of Ni system be substrate metal layer 1 to Fe system net 3a and strongly, can obtain the larger lining material of engaging force. In this occasion, also can use for example the net 3b of Ni system to be sandwiched in two three-layer structure wire nettings between the net 3a of Fe system.
On the other hand, as diverse ways therewith, also can consist of than resistance inequality material the in length and breadth wire rod of wire netting 3, adjust the resistance value of wire netting integral body by its Texture composition of materials. Fig. 8 a and 8b show its concrete example, and a group 16 of the metal wire rod that intersects is made of stainless steel, and another group 17 is then by consisting of than its less carbon steel than resistance. This carbon steel wire rod 17 for corrosion protection, can use the surface with the zinc product of coating in addition. And also substitutable carbon steel utilizes take Ni or Cu as principal component, and is that little alloy forms wire rod group 17 than resistance ratio stainless steel. In addition, shown in Fig. 8 c, also can respectively organize in the wire rod in length and breadth, make the different wire rod of material 18 and 19 mutual assortments and consist of.
Secondly, wire netting 3 is except making in establishment wire rod mode, also can use laths of metal net 33, it is as shown in Figure 9, to be become jagged metallic plate by holomorphism along many joint-cuttings that the thickness of slab direction connects, the Direction distortion that the formation direction of itself and this joint-cutting is intersected makes joint-cutting towards this deformation direction opening, so as to forming mesh. This laths of metal net 33 can be with for example making as device 34 shown in Figure 10.
(1) elevating mechanism is used so that 37 liftings of lifting sword.
(2) transverse moving mechanism is used so that lifting sword 37 moves towards horizontal side with respect to the metallic plate 35 on the platform 36.
(3) plate sending mechanism is used so that the metallic plate 35 on the platform 36 is sent with a constant pitch off and on towards 37 corresponding end side of lifting sword.
And, in lifting sword 37 bottoms, there are many blades 39 to be formed wavy. And along the rising wood of platform 36, be formed with the blade 38 corresponding to this blade 39. In addition, 40 are the pressing member in order to prevent that metallic plate 35 from floating.
Make flowing mode about it, such shown in Figure 11 a, make metallic plate 35 from outstanding pitch of end face portion of platform 36, lifting sword 37 is descended, then metallic plate 35 is between 39 corresponding inner edge portion of blade of the blade 38 of platform 36 sides and lifting sword 37 sides, and through-thickness is cut off, and forms the joint-cutting 41 of dotted line shape, simultaneously because this joint-cutting 41 just is subject to the downward pushing of blade 39 from the divided protuberance 42 of metallic plate 35 bodies. This protuberance 42 that is subjected to pushing downwards is by being out of shape and opening towards the below from joint-cutting 41.
Secondly, as shown in Figure 11 b, risen by lifting sword 37, it is moved towards transverse direction be equivalent to rough half the distance of joint-cutting 41 length, also make metallic plate 35 give prominence to again a pitch by platform 36 ends. Then, lifting sword 37 is descended, and according to the mechanism same with Figure 11 a, one side is being roughly parallel to established joint-cutting 41, and half the position (also being engrail) that is offset each joint-cutting 41 length forms new joint-cutting 43, and one side pushes away its protuberance 44 towards the below. Mode is just such shown in Figure 11 c whereby, forms diamond-shaped meshes in a row 45 by this protuberance 44 and the protuberance 42 that before forms along platform 36 widths. Secondly, lifting sword 37 is risen, make lifting sword 37 with above-mentioned opposite direction, be back to original position towards transverse shifting, device 34 just returns back to the state shown in Figure 11 a. Below, repeat same step, can form laths of metal net 33 shown in Figure 9. And, also can use shown in Figure 11 d like that, utilize calendar rollers 33a to apply calendering to the laths of metal net 33 that so obtains.
For example, the occasion that is engaged with the substrate metal layer 1 of carbon steel system at the corrosion resistant metal sheet material 4 that utilizes laths of metal net 33 (for example Fe is the laths of metal net) with Ti or Zr system, if the thickness of corrosion resistant metal sheet material 4 is T, and be M in order to the plate thickness of making laths of metal net 33, then the value of M/T should be set in the scope of 0.1-0.6. If M/T is less than 0.1, then laths of metal net 33 is invaded the degree deficiency of corrosion resistant metal sheet material 4, and bond strength is low. If surpass 0.6 again, then invade excessive on the contrary, the mesh of laths of metal net 33 floats to the surface of corrosion resistant metal sheet material 4, cause bad order, or a part of mesh of laths of metal net 33 passes the face side of corrosion resistant metal sheet material 4 and produces and break etc., may cause the corrosion protection result impairment to substrate metal layer 1. The value of M/T is advisable with 0.2-0.5.
On the other hand, as shown in Figure 9, the interval D of diamond-shaped meshes 45, if with its mean value [also being (R+S)/2] that is defined as the size S of the size R of long-diagonal and short diagonal, then D/M should be set in the scope of 1.1-40. If D/M is less than 1.1, then mesh spaces is too small, and the depth of invasion of laths of metal net is not enough, and bond strength is on the low side. On the other hand, if D/M surpasses 40, the mesh density of then invading to the corrosion resistant metal sheet material 4 is excessively thin, causes that to engage effect on the low side. The value of D/M should be at 2-30.
The above-mentioned lining material that below just has Fe and be the substrate metal layer is illustrated use-case. Figure 12 a, b show that substrate metal layer 1 forms lining material 10 examples cylindraceous. Corrosion resistant metal sheet material 4 is to be configured to lid to cover cylinder inner face (or outside: to this occasion at this moment, otherwise in Figure 12 a, b the position relationship of substrate metal layer 1 and corrosion resistant metal sheet material 4 can), and weld seam weld portion 8 can be shown in Figure 12 a like that, circumferencial direction along cylinder is formed with many, and axially forming by set interval along cylinder; Or can shown in Figure 12 b like that, form helical form; Or can be shown in Figure 12 c like that, along cylinder circumferentially by set interval form along Cylindorical rod to many linearities. This shape for example can be applicable at the metastomium of tower groove class or heat exchanger, and perhaps pipe inner face or outside apply the occasion of corrosion resistant metal coating etc.
Figure 13 a, b represent that the substrate metal layer is formed the example of hollow cone shape or circular cone shape, and corrosion resistant metal sheet material 4 is configured in its inner face side. And weld seam weld portion 8 can be like that along its circumferential formation shown in Figure 13 a, or form along its bus like that shown in Figure 13 b. This shape can be applicable to the diameter shrinkage part of tower groove class top for example or bottom.
At this, corrosion resistant metal sheet material 4 also can utilize the mode such as welding (such as the TIG welding) to be divided in advance mass part and be engaged, and is covered in the comprehensive shape of inner face and form. Figure 15 g represents to be divided into radial corrosion resistant metal sheet material 4 and example that form. Its radial docking section utilizes seam weld portion 9 to be engaged and integrated, and recycling weld seam weld portion 8 engages with substrate metal layer 1. And weld seam weld portion 8 is to avoid seam weld portion 9 and the formation concentric circles. On the other hand, in the example shown in Figure 15 e and Figure 15 h, corrosion resistant metal sheet material 4 is cut apart conglobate inside portion 4a and the outside portion 4b that encloses pie by the circular dividing face, and outside portion 4b is more cut apart by radial, and its docking section is separately engaged by seam weld portion 9. And substrate metal layer 1 may be partitioned into corresponding to the inside part of corrosion resistant metal sheet material 4 inside portion 4a and other parts (Outboard Sections) and forms. In this occasion, also can be for this divided inside portion and Outboard Sections, respectively corrosion resistant metal sheet material 4 is engaged by weld seam weld portion 8 in advance, relend thereafter by the substrate metal layer 1 of the modes such as welding with these inside parts and Outboard Sections and engaged each other with corrosion resistant metal sheet material 4 each other.
Figure 16 a-c represents the substrate metal layer is formed the example of square tabular lining material. Figure 16 a represents to have many towards the weld seam weld portion 8 of extending along lining material 10 1 edge directions, presses set interval side by side and the example that forms crisscross with it. Figure 16 b is the both ends side in this and row arrangement weld seam weld portion 8, disposes along the example of extension weld seam weld portion 8 crisscross with it. Figure 16 c represents to be formed with the example that extends weld seam weld portion 8 from the central radial of plate. And, shown in Figure 17 a, b, for the occasion that is formed with jut 10b at substrate metal layer 1 plate face, also can avoid this jut 10b and form weld seam weld portion 8.
Figure 18 a, b are illustrated in the plate face that is formed thick plate-like substrate metal layer 1 and form more shallow recess 1a, the corrosion resistant metal sheet material 4 of correspondingly-shaped is embedded wherein, and only form the example of weld seam weld portion 8 in these corrosion resistant metal sheet material 4 edges. In addition, Figure 19 a, b represent lining material 10 is applied to the example of heat exchanger tube sheet 71. Its manufacture method is to form many through hole 40a at substrate metal layer 1 and corrosion resistant metal sheet material 4 in advance, and this corrosion resistant metal sheet material 4 is stacked and placed on the end face of substrate metal layer 1, forms weld seam weld portion 8 at its stacked. Secondly, utilize the welding mode to make this substrate metal layer 1 and barrel cylindraceous 50 integrated. Again tubing 40 is inserted in each through hole 40a of substrate metal layer 1, under the end face that makes them state consistent with each other, with the circumference of tubing 40 and corrosion resistant metal sheet material 4 is fixed and welding.
More than, the example that just has Fe and be a substrate metal layer lining material in addition explanation, it is that the example of substrate metal layer lining material is illustrated that the below will have Cu with that. At this, about the manufacture method of lining material, for having the lining material that Fe is metal level, owing to can use and according to the mode of the illustrated roughly the same principle of Fig. 1 and Fig. 2, so mainly just will be illustrated with its dissimilarity.
At first, in situation shown in Figure 20, to be that substrate metal layer 51 for example forms Sn-37 % by weight Pb alloy-layer (hereinafter referred to as solder layer) 52 as intermediate metal layer at Cu, lamination metal net 53 and as the corrosion resistant metal sheet material 54 that is consisted of by Ti, Zr etc. of corrosion resistant metal coating thereon, thus laminated body 55 formed. Sn-Pb alloy-layer 52 both can be by having stirred into pulpous state (solder paste) with alloy powder and scaling powder, and coated substrate metal level 51 surfaces form, and also can use Alloy Foil, or form the melting electrodeposited coating.
Secondly, wire netting 53 is as adopting intersect shown in Fig. 8 a-c in the metal wire rod one group 56 to consist of with stainless steel, and another group 57 consists of with Cu. Switching in laminated body 55 occasions that contain this kind wire netting 53, and to have Fe be that the lining material occasion of substrate metal layer is same that near resistance heating the less wire netting 53 of energising sectional area is larger. At this, because the Cu wire rod section 57 of wire netting 53 is lower than resistance, so resistance heating mainly is to produce in STAINLESS STEEL WIRE section 56 and with the contact site of corrosion resistant metal sheet material 54 or solder layer 52. And the structure of seam weld portion 58 is to be presumed to shown in Figure 21 like that. Also namely, STAINLESS STEEL WIRE section 56 exerts pressure by roller electrode 6 (Fig. 1 etc.) in the wire netting 53, and towards invading deeper because of softening corrosion resistant metal sheet material 54 sides of resistance heating; Simultaneously, Cu wire rod section 57 is by the solder layer 52 that melts because of resistance heating, is that substrate metal layer 51 engages with the soldered form of what is called and Cu. So, infer by people that corrosion resistant metal sheet material 54 and Cu are that substrate metal layer 51 namely is situated between and is engaged one another formation lining material 20 by wire netting 53 with solder layer 52.
For example, be that corrosion resistant metal sheet material is the occasion that the substrate metal layer engages with Cu making Ti or Zr, if making the thickness of corrosion resistant metal sheet material is T, the wire diameter of wire netting is M, the interval of mesh (in abutting connection with the inboard of wire rod to each other, also be the interval in space) for D, be the preferred range that the lining material occasion of substrate metal layer has M/T and D/M equally with using Fe then. In this occasion, the value of M/T is 0.1-0.4, is preferably 0.15-0.3; The value of D/M is 1-10, is preferably 1.5-7.
Below, the above-mentioned lining material that just has Cu and be the substrate metal layer is illustrated use-case. At first, in the example shown in Figure 22 a, substrate metal layer 51 possesses and has: body 51a, be formed grow crosswise tabular; Protuberance 51b gives prominence to towards the top and forms from the both ends of body 51a; And tabular extension 51c, stretch out towards the transverse direction outside from the upper end of each protuberance 51b. What respectively contain two plate faces is to cover with corrosion resistant metal sheet materials 54 such as Ti, Zr comprehensively; And be formed with weld seam weld portion 58 at body 51a and extension 51c.
Figure 22 b represents the profile of this body 51a. Be formed with solder layer 52 on the two sides of substrate metal layer 51, lamination has wire netting 53 as shown in figure 20 thereon, more is covered in its integral body with corrosion resistant metal sheet material 54. Corrosion resistant metal sheet material 54, in substrate metal layer 51 edge side on one side, its edge, both sides connects by weld portion 59, and substrate metal layer 51 is encased. And, under this state, by utilizing roller electrode 6 to implement the mode of weld seam welding, can form simultaneously weld seam weld portion 58 on the two sides of substrate metal layer 51. At this, weld seam weld portion 58 is extended along its lengthwise for body 51a, then stretches out direction along it for extension 51c and extends, and respectively is formed with many with set interval respectively. The lining material 20 of this shape can be applicable to be used in and electroplates or the electrode of various electrolytic treatments etc. or to the flat wire of electric usefulness etc. Especially applicable to extension 51c being configured in the outer portion of terminal as power supply usefulness of electrolyte; And with body 51a as liquid infiltration type flat wire, also namely under the state that itself is impregnated in the electrolyte, as suspended portion such as by the suspended portion such as basket of plating component or plated material support usefulness.
Secondly, for shown in Figure 23 a-d, be formed the bar-shaped or shaft-like substrate metal layer 51 with circle or square profile shape, available corrosion resistant metal sheet material 54 covers its outer peripheral face and forms weld seam weld portion 58. Weld seam weld portion 58 is the longitudinallies along bar-shaped or shaft-like substrate metal layer 51, is formed with many circumferential of its section with set interval. And in Figure 23 b and 23d, substrate metal layer 51 is to be formed hollow shape. The product of these shapes is also applicable to electrode matrix or flat wire etc.
