摘　　要：采用四球摩擦磨损试验机考察了表面修饰纳米铜添加剂(简称纳米Cu)和磷酸三甲酚酯(T306)单剂及两者复配体系的摩擦磨损性能,采用X射线光电子能谱仪(XPS)和扫描电子显微镜(SEM)对磨痕表面进行了分析。结果表明,纳米Cu具有良好的润滑性能;当其在一定浓度范围内与T306复合使用时,两者将产生协同抗磨减摩效应;且两者添加的质量分数各为0.5%时,复配体系的抗磨效果最佳。两者复合使用时,会在摩擦表面形成由单质Cu的沉积膜及FeS、SO42-和PO34-的化学反应膜组成的复合表面膜,产生了协同抗磨减摩作用。The effects of Cu nano-particles additive （Nano-Cu） and tricresyl phosphate （T306） and their synergetic effects on the tribological performance of lube oil were investigated by using four-ball test machine. The interaction of the two additives was also studied through SEM and XPS analysis. The results showed that the two additives with a certain range of concentration could improve tribological properties of base oil. The synergetic effect of the extreme pressure and antiwear was found in the lube oil containing nano-Cu and T306. When the mass fractions of the two additives in lube oil were 0.5% respectively, the extreme pressure and antiwear properties of the complex system were best. The composite film made by the aggradation film of Cu and the tribochemical reaction film containing FeS, SO4^2- and PO4^3- was found on the rubbing surface, which was the reason of svnergetic effect.
