Example Embodiment
[0018] The present invention will be further explained in conjunction with the drawings and embodiments, such as figure 1 As shown, the present invention uses gas nitriding to form the pretreatment layer 2 on the surface of the steel substrate 1, and then coats the wear-resistant layer formed by the multi-element nano-film of chromium nitride and titanium nitride in a multi-arc ion plating equipment 3. The wear-resistant layer 3 is formed by laminating chromium nitride and titanium nitride. The layered film thickness is 200~500nm, the hardness is 2000~2600HV, and the total thickness is 6μm, which is more resistant than the steel ring with only nitride layer. Can be increased by 3 times. The first or outermost layer of the multi-element multilayer nano-film wear-resistant layer 3 is coated with a chromium nitride layer. The pretreatment layer is a nitride layer, or a pure titanium layer, or a chromium nitride layer.
