Problems solved by technology

[0007] The above patents form a certain thickness of coating on the surface of steel parts by cladding, doping graphene, rare earth passivation or forming a layer of silane film. Although these methods have correspondingly improved the corrosion resistance of the steel parts to be protected, However, the above patents did not solve the problem that the protective effect of the coating on the steel parts is not good enough in different environments. At the same time, it did not solve the problem that the graphene and silane films were damaged under stress, strain and different corrosion. The self-healing ability of graphene and silane film is poor, and the performance indicators such as anti-friction performance, surface hardness and strength of the different coatings prepared by the above patents are not very good, etc.
