通过电镀，可以在机械制品上获得装饰保护性和各种功能性的表面层，还可以修复磨损和加工失误的工件。
Through the electroplating, can be in mechanical products won adornment of protective and various functional surface layer, still can repair wear and processing error of workpiece.
这种结构形成了抗磨损的优化表面层和抗腐蚀的钝化层，明显改善了材料表面抗磨损、抗疲劳和抗腐蚀特性。
This structure forms the passivation layer against corrosion and wear. The optimum layer against wear improves the resistance of material surface in corrosion, wear and fatigue extremely.
化学气相沉积的碳化物镀层一般很耐磨，但这些表面层镀后的粗糙度较高，会使与之相配的试件受到剧烈磨损。
In general, the carbide coating of chemical vapour deposition resists wear. But these surface coatings have a high roughness, which causes violent wear in the matched test pieces.
