Abstract: The nano-materials' unique performance causes it to demon strate in the lubrication domain good anti-rubs the anti-friction effect. The nanometer lubricant additives， the domestic and foreign development present situation and the research level were summarized. In order to real ize the inorganic nano-particles in lubricating oil， even dispersion was carried on the surface treatment to nano-particles. The surface modified methods for the nanometer lubricant additives mainly had coating modifi cation and surface chemistry modification. The massive experiments in dicated that if the nanoparticles w ere added to the lubricants， anti-wear would not only play a role in reducing friction， but also be extended e quipment life， reduce pollution， energy conservation， the mainte nance-free as possible. 

Keywords: wear-resistance and anti-friction; lubricant additive; surface modification
