Of the present invention can carrying out coating-plating, mix coating, replace coating be processed as metals ion wire rods such as special-purpose gold (Au), silver (Ag), copper (Cu), iron (Fe), tin (Sn), zinc (Zn), aluminium (Al), magnesium (Mg), titanium (Ti), nickel (Ni), platinum (Pt) and other alloy according to the common process technology.The metals ion wire rod dissolves (420 ℃～660 ℃ of fusing points) through arcing device (normal temperature electric arc) flash; Utilization high speed variable frequency drive motors; With metals ion through conduit be coated with along shower nozzle be plated to by coating object (like various starting material such as metal, plastics, timber, pottery, glass, stone, leather, cloth, paper product, concrete products) surface on; Solidify immediately and form that one deck is anticorrosion, antirust, (thickness can freely be set up for the metal level decorateed; Coated layer thickness 50 μ m～120 μ m can be according to being constructed by the actual requirement of coating object), and it is just passable only need to be done the polishing pre-treatment of simply sandblasting by the object of coating.
As shown in Figure 4, be the spontaneous potential variation diagram after the salt spray testing on surface behind normal temperature zinc of the present invention, the aluminum metal ion flash fusion coating.Can know that by Fig. 4 normal temperature metal ion flash melt surface bed thickness is 75um; Normal temperature zinc/duraluminum belongs to the spontaneous potential change curve (the single-point line among the figure) of ion flash fusion plated surfaces, can find out: spontaneous potential value (variation range: 1-0.9-v/Ag.AgCl) on a declining curve with the prolongation of brine spray time.
The change curve (two dot chain line among the figure) of zinc/Aluminum Alloy Room Temperature metals ion flash melt surface coating; Can find out: spontaneous potential value (variation range: 1-0.5-v/Ag.AgCl has weight break point at 0.9 and 0.6 place respectively) is on a declining curve with the prolongation of brine spray time.
The change curve of aluminum ion metal coating (dotted line among the figure), can find out: spontaneous potential value (variation range: 1.1-0.7-v/Ag.AgCl has weight break point at 0.88,0.78 and 0.22 place respectively) is on a declining curve with the prolongation of brine spray time.
The change curve of zine ion metal coating (the single line among the figure), can find out: spontaneous potential value (variation range: 1.2-0.55-v/Ag.AgCl has weight break point at 1 and 0.55 place respectively) is on a declining curve with the prolongation of brine spray time.
The spontaneous potential of iron (long and short dash line among the figure), can find out: the spontaneous potential value is 0.65.
Application of the present invention is very extensive, can be applicable to buildings, storage tank farm, bridge, head tower, boats and ships, vehicle, furniture, household electrical appliances, pillar steelframe, military equipment, motorway and public transit facility etc.This device not only can improve antiseptic and rustproof property and weather resistance, and can be once crosses problems such as solving the arrangement that is coated with plating piece, environmental pollution, construction quality, can not produced any influence to being coated with plating piece, and is safe and reliable.No matter be operation under water; Or construction under the hot weather environment, can both operate freely, this device all is that site operation provides the feasibility of filling part; Be conventional process techniques such as alternative chemical plating, spraying; Than Technologies such as traditional chemical plating, spraying antirust, antiseptic power is high more than 6 times, and can prevent that salt damage and acid rain from corroding, once coating; Antirust, rot-resistant was valid up to 15～20 years, and its outstanding feature is high-quality, efficient, economy, less energy-consumption, with low cost, safe and reliable etc.Antirust, anticorrosion industry is produced greatest benifit, is to have opened up field service frontier such as anticorrosion, antirust, embedding decoration.This device maintains the leading position at home, and the occupation rate prediction in market is minimum about 30%～50%.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Former every technical scheme content of the present invention that do not break away from, all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present invention.
