Abstract
A sliding parts is used for all equipment like information instruments, including the car industry and the office equipment, optics, and the medical treatment, etc. Then, this research did the compound surface modification to the pure iron so that the functionality of a sliding parts might improve. It eased and Namac did the Me-DLC coating of the hardness difference in the layer in five kinds of middle (Non-Electrolyte Ni Plating, Ion Nitriding, Radical Nitriding, super-NV Nitriding, Pionite Processing). The following things were performed in this research. A detailed experiment on the friction characteristics inclination of the next generation surface coating was done. Examine a basic friction abrasion mechanism in detail It is a necessary, indispensable for develop an excellent sliding parts in wear-out of the more friction basic knowledge.
