Abstract
The invention discloses a production method of an aluminum-covered cylinder sleeve. The aluminum-covered cylinder sleeve comprises an alloy cast iron layer and an aluminum layer in sequence from inside to outside; a pure copper combination layer is arranged between the alloy cast iron layer and the aluminum layer; and composite thin film ceramic is attached to the inner wall of the alloy cast iron layer. Compared with the prior art, the production method disclosed by the invention has the beneficial effects that the cylinder sleeve integrates the advantages of a cast iron cylinder sleeve and a steel cylinder sleeve, has the characteristics of high rigidity and high toughness, and can obviously improve the fatigue strength; furthermore, a layer of ceramic thin film is formed on the inner surface of the cylinder sleeve, so that the high-temperature hardness of the cylinder sleeve is increased, and the inner surface of the cylinder sleeve has self-lubricating property; friction is relieved; and metal and ceramic elements are diffused in two directions, so that a composite film structure is firm and falling-free.
Description
Technical field
The present invention relates to a kind of cylinder jacket production technical field, more particularly, to a kind of production method of aluminium containing cylinder jacket.
Background technology
In order to reduce automobile fuel consumption and reduce exhaust emissions, all-aluminium engine arises at the historic moment, and is American-European engine manufacture enterprise
The new product that industry was developed in recent years, domestic at the early-stage, it is the developing direction of light car engine.
Because aluminium and the direct coefficient of friction of aluminium are more much higher than the coefficient of friction between aluminium and cast iron, main flow solution at present
Certainly method is edge cast iron cylinder cover in aluminum cylinder, and Cast iron liner is that aluminium engine realizes low emission, low oil consumption core, how to make
It is successfully to develop one of key technology of all-aluminium engine and production domesticization that cast iron cylinder cover and aluminum cylinder are combined closely.
In order that cylinder jacket wear-resisting, anti-attrition under high temperature, the adverse circumstances of high pressure, people are oozed to interior surface of cylinder liner
Pottery is processed, and domestic and international similar technique is to spray the ceramic coated powder in normal direction metal surface with flame spraying or high-temperature plasma,
Its shortcoming is because the thermal coefficient of expansion of pottery, metal bi-material has big difference, and easily coating shedding occurs, additionally, high during spraying
Warm ceramic powder can cause metal surface hot-spot to damage matrix material.
Content of the invention
It is an object of the invention to provide a kind of aluminium contains the production method of cylinder jacket, make that cylinder jacket is wear-resisting, anti-attrition, resistance to height
Temperature, thus improving engine power, reducing oil consumption, reducing exhaust emission.
For achieving the above object, the present invention adopts following technical proposals：
A kind of aluminium contains cylinder jacket, includes alloy cast iron layer, aluminium layer, described alloy cast iron layer and aluminium layer outward successively by interior
Between be provided with fine copper binder course, the inwall attachment laminated film pottery of described alloy cast iron layer.
Manufacture the method that described aluminium contains cylinder jacket, comprise the following steps：
Step one：Process the alloy cast iron layer of cylinder jacket first, process fixing work in the outer wall of described alloy cast iron layer
Forward-reverse spiral groove, then in outer wall plating or the spraying pure copper layer of alloy cast iron layer, such alloy cast iron and cast steel can be more
Good combination infiltration；
Step 2：Pour into a mould aluminium layer in the outer wall of alloy cast iron layer；
Step 3：Cylinder jacket is placed on and oozes in pottery stove, energising preheating 2.5 hours, temperature is risen to 255 DEG C ± 5 DEG C -265 DEG C
±5℃；
Step 4：Vacuumize, open vavuum pump, make to ooze the vacuum control made pottery in stove in the range of 45Pa-48Pa；
Step 5, it is passed through nitrogen, silane, borine, be passed through and oozed by the borine of the nitrogen of 75-77%, the silane of 12-14%, 11-13%
In pottery stove, and control flow, keep oozing the vacuum in pottery stove；
Pottery is oozed in step 6, insulation, cylinder jacket is oozed the Control for Kiln Temperature of pottery stove in the range of 265 DEG C ± 5 DEG C, insulation goes out for 8 hours
Stove；
Step 7：Cooling is come out of the stove.
The present invention compared with prior art, has the advantages that：
The cylinder jacket of the present invention has the characteristics that rigidly good, toughness is high, can significantly improve fatigue resistance, and in cylinder jacket
Surface obtains one layer of ceramic membrane, both increased the high temperature hardness of cylinder jacket, and had made inner surface of cylinder liner have self lubricity again, reduces
Friction, metal and ceramic element directional diffusion, structure of composite membrane firmly will not fall off.
Specific embodiment
With reference to specific embodiment, the present invention is done and supplement further, but limit the present invention never in any form.
A kind of aluminium contains cylinder jacket, includes alloy cast iron layer, aluminium layer, described alloy cast iron layer and aluminium outward successively by interior
It is provided with fine copper binder course, the inwall attachment laminated film pottery of described alloy cast iron layer between matter layer.
Manufacture the method that described aluminium contains cylinder jacket, comprise the following steps：
Step one：Process the alloy cast iron layer of cylinder jacket first, process fixing work in the outer wall of described alloy cast iron layer
Forward-reverse spiral groove, then in outer wall plating or the spraying pure copper layer of alloy cast iron layer；
Step 2：Pour into a mould aluminium layer in the outer wall of alloy cast iron layer；
Step 3：Cylinder jacket is placed on and oozes in pottery stove, energising preheating 2.5 hours, temperature is risen to 255 DEG C ± 5 DEG C -265 DEG C
±5℃；
Step 4：Vacuumize, open vavuum pump, make to ooze the vacuum control made pottery in stove in the range of 45Pa-48Pa；
Step 5, it is passed through nitrogen, silane, borine, be passed through and oozed by the borine of the nitrogen of 75-77%, the silane of 12-14%, 11-13%
In pottery stove, and control flow, keep oozing the vacuum in pottery stove；
Pottery is oozed in step 6, insulation, cylinder jacket is oozed the Control for Kiln Temperature of pottery stove in the range of 265 DEG C ± 5 DEG C, insulation goes out for 8 hours
Stove；
Step 7：Cooling is come out of the stove.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
