通过对目前润滑油脂添加剂研究成果的综合分析，提出了当前研究中存在的一些问题以及今后应关注的研究方向，特别强调应重点加强特殊环境，如高温、重载、磨损表面的修复、环境友好等条件下的纳米润滑添加剂的研制，纳米微粒润滑机理与其特殊的摩擦学性能之间的关系，以及表面修饰纳米微粒的工业化研究。

Friction and Wear of Nanoparticles in Lubricants--Present Status and Development Trends

Nanoparticles as lubricant additives have gained more and more attention in reducing friction and wear under high temperature, high load conditions, repairing ware metal surface and protecting ~environment .Some nanoparticles as copper, diamond, oxides, sulfides, rare earth fluorides as lubricant additive are found to have excellent properties of reducing wear and ~increasing loadcarrying capacity. Some problems and concerns in the investigation of nanoparticles as lubricant additive are presented. It is suggested to focus on the study of the friction and wear in such special conditions as high ~temperature , high load, healing on worn metal surface, the ~lubricating mechanism of ~nanoparticles and the ~largescale production of the modified nanoparticles.
