Description
Technical field
The invention belongs to metal material surface coating technology fields, and in particular to a kind of quickly free of contamination galvanized method.
Background technology
Zinc-plated is the most common anti-corrosion method in metal surface, and current most common galvanized method is electrogalvanizing and hot dip
Zinc.Mechanical zinc-plating technology is needed using zinc powder, surfactant, deposition activator, inorganic additives etc., and process is complicated,
Environmental pollution is big.Hot Galvanizing Technology usually requires to wait for that galvanized sheet material immerses in high temperature zinc liquid, also needs to carry out spy after obtaining coating
Different cooling technique, complex process, high energy consumption.It is the complex process of above two galvanized method, of high cost and inevitably right
Environment brings certain pollution.Patent publication No. is " the mechanical zinc-plating agent titanium alloy plating process " and patent of 101348909 B of CN
" mechanical zinc-plating process " of 103334100 A of Publication No. CN is disclosed to be obtained on the surface of the workpiece using the method for mechanical plating
The new process of coating is obtained, but the method for above-mentioned patent disclosure is still needed to using a variety of additions such as impact media, initiator, passivating solutions
Agent, energy loss is big, and processing step is more, and process is complicated.
Invention content
Technical problem to be solved by the present invention lies in view of the above shortcomings of the prior art, provide one kind quickly without dirt
The galvanized method of dye.The galvanized method is quickly obtained zinc coating using the method that sliding friction is handled in sheet metal surface, should
For method without multiple additives such as impact media, initiator, passivating solutions, basic energy free loss can be quickly pollution-free

Device disclosed in the method for making Nano surface of metal material ", by the device, galvanizing process is easy, controllable, and zinc coat
Strong with metal matrix material binding force, any crackle and other defect is not present in junction.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of quickly free of contamination galvanized method,
It is characterized in that, this method is：There is the zinc ball of 500N~900N load to be pressed on sheet metal load, controls the metallic plate
Material moves reciprocatingly in X direction so that zinc ball is in the sheet metal surface sliding friction, when sheet metal is back and forth transported in X direction
At dynamic one time, control the sheet metal along Y-direction translate 200 μm~800 μm after move back and forth in X direction again, persistent movement
A sliding friction process is completed to the surface of sheet metal, repeats a sliding friction process 20~90 times, finally
Zinc coat is obtained on the surface of sheet metal, the Vickers hardness of the sheet metal is higher than zinc ball.
The principle of above-mentioned galvanized method is：The hardness of zinc ball is less than the hardness of sheet metal, when sheet metal is carried in load
When the zinc ball downslide dynamic friction of lotus, zinc ball is worn, and the zinc in zinc ball is constantly cold-welded to metal under the effect of friction
Plate surface forms mechanical snap or metallurgical binding, thus, a sliding friction process is repeated as many times, you can in metal
Plate surface obtains zinc coat.
A kind of above-mentioned quickly free of contamination galvanized method, which is characterized in that gold during the sliding friction processing
