Abstract
A method used in Mg alloy work piece surface process is first of all to blast sand to the being sprayed Mg alloy work piece surface, then to spray within 2 hours after the sane blast; first preheating then spraying the surface with pure Al wire to form an Al coating, after that put it for thermal insulation under 410-430deg.C finally sealing it with diluent and sealing agent then to bake it in a heat process furnace to solidize the agent. A smelt connection is formed between the Al layer and the Mg alloy matrix.
Description
Technical field
The present invention relates to the plating of metallic substance to material, is a kind of molten state clad material sputtering process.
Background technology
Magnesium alloy has the performance of a lot of excellences as the lightest structural metallic materials, is described as the most promising green structured material of 21 century.But the erosion resistance of magnesium alloy is relatively poor, and this has become the biggest obstacle of its application.Surface treatment method of Mg alloy adopts chemical conversion film, differential of the arc anodizing more, is formed with organic coating, coating etc., because protective layer and matrix mostly are non-metallurgical binding, so bonding force is very low, protective layer easily comes off, and causes environmental pollution easily.
Summary of the invention
The purpose of this invention is to provide the method that magnesium alloy work-piece surface is handled, make that coating is firm, corrosion resistance nature is high, technology is simple, be convenient to operate.
The present invention is used for the method that magnesium alloy work-piece surface is handled, magnesium alloy work-piece surface that will spray treatment is carried out sandblasting in advance, after sandblasting 2 hours with the interior spray treatment of carrying out, before the spraying magnesium alloy workpiece is carried out preheating, adopt high-purity aluminium wire to spray, form aluminum coating at magnesium alloy work-piece surface, then magnesium alloy workpiece is handled 410-430 ℃ of insulation, adopt thinner and hole sealing agent to carry out sealing treatment at last, in heat treatment furnace, toast then, hole sealing agent is solidified.
The preheating temperature of before the spraying magnesium alloy workpiece being carried out preheating is 250 ℃, after magnesium alloy work-piece surface spray aluminum coating, is incubated processing 2-3 hour at 410-430 ℃.
To magnesium alloy work-piece surface carry out in advance sandblasting used be cleaning exsiccant emergy, granularity is 0.8～1.5mm.
The output voltage that carries out electric arc spraying is 38-40V, and electric current is 140-150A, and air pressure is 0.55-0.6Mpa, and the Surface Vertical of spray gun and magnesium alloy workpiece, the distance between magnesium alloy work-piece surface and the nozzle are about 60mm.
Adopting thinner at last is dehydrated alcohol, and hole sealing agent is a dry air type resol, and both volume ratios are 1: 1-1: 2, in 100-150 ℃ heat treatment furnace, toast 5-30min then.The thickness of the aluminum coating of described formation is 50-100 μ m.
The invention has the beneficial effects as follows: compare with existing magnesium alloy treatment process method, form the metallurgical binding layer between aluminum coating that electric arc spraying forms and the magnesium alloy substrate, coating and matrix bond are firm, corrosion resistance nature is high.Its technology is simple, be convenient to operation, environment is not polluted.
