Background technology
With the parts that metal material processing such as steel, non-ferrous metal, cast iron form, be the chief component of industrial equipment, instrument, mould.Along with economic development and continuous advancement in technology, to the surface property of various components of machine, requirement especially corrosion-resistant, abrasion resistance properties is more and more higher.Tradition is to adopt electro-deposition method to be coated with hard chrome, Ni at piece surface, or adopts surface heat-treatment process that piece surface is handled, the performance requirement that has satisfied part of these method parts, but there is following shortcoming:
1, seriously polluted, the especially pollution that electrodeposition technology caused;
2, under abominable service condition, easily lost efficacy, as in parts such as piston rod, piston ring, easy to crack under the hard chromium high load condition, come off.
3, can't adapt to complicated service condition, as: under the high-temperature oxydation condition, under the high capacity, stack occasion such as corrosion-resistant, traditional hard chrome is coated with, surface heat is handled and often can't be met the demands.
For these reasons, the searching cost is lower, functional characteristics outstanding, the strong and environment friendly and pollution-free surface treatment method of adaptability is the striving direction of scientific research and industrial quarters always.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, provide a kind of composite coating and preparation method who is used for component of machine surface abrasion resistance damage, corrosion-resistance treatment, in the hope of the advantage that all can obtain to give prominence on the environmental-protecting performance in production cost, product function and production process.
