摘要/Abstract

摘要： 采用多弧离子镀技术分别制备了Ti-Ag/TiN-Ag和Ti-Cu/TiN-Cu镀层，同时制备了以石墨烯为导电填料和聚乙二醇聚丙二醇单丁基醚（PAG）为基础油的导电润滑脂（GLG）。用HFT-R4000高速往复载流摩擦磨损试验机研究了镀层在载流润滑条件下的摩擦磨损性能，镀层和磨痕表面用扫描电子显微镜（SEM）、能量色散X射线光谱仪（EDS）和拉曼光谱仪（Raman）进行观察和分析。结果表明，铜（Cu）原子分数为3%时，Ti-Cu/TiN-Cu镀层在脂润滑下具有较好的抗磨减摩及电腐蚀性能；银（Ag）原子分数为3%时，Ti-Ag/TiN-Ag镀层在脂润滑下展现出更好的电流稳定性，这归因于镀层、润滑脂和电流产生的热在表面形成了复杂的保护膜，提高了摩擦副的减摩和抗磨作用。

Abstract: The Ti-Ag/TiN-Ag and Ti-Cu/TiN-Cu coatings are prepared by multi arc ion plating. The conductive grease(MLG) is prepared with multilayer graphene(MLG) as conductive filler and polyethylene glycol(PAG) as base oil. The friction and wear properties of the coating under the condition of current carrying lubrication are studied by hft-r4000 high-speed reciprocating current carrying friction and wear tester. The surface of the coating and wear mark are observed and analyzed by scanning electron microscope(SEM), energy dispersive X-ray spectrometer(EDS) and Raman spectrometer(Raman). The results show that the Ti-Cu/TiN-Cu coating with Cu atom content of 3% has better anti-wear, anti-friction and electro-corrosion properties under grease lubrication, while the Ti-Ag/TiN-Ag coating with Ag atom content of 3% shows better current stability under grease lubrication, which is attributed to the composite effect between the coating and grease to improve the friction reduction, anti-wear and conductivity of the friction surface.

Key words: current carrying friction, conducting medium, conductive coating, conductive grease
