摘　　要：为提高传统齿轮油的摩擦学性能,采用四球试验机研究了加入纳米镍粉、镍铜粉复配粉体和纳米金属粉与超细蛇纹石粉复配粉体的情况下粉体加入量及复配比例对齿轮油摩擦学性能的影响,并研究了其载荷特性。结果表明:含纳米镍铜粉复配粉体的齿轮油比含单一粉体齿轮油的摩擦学性能更好,当纳米镍粉与铜粉的质量比为3∶1、粉体总加入量(w)为0.1%时,试验摩擦因数和磨斑直径比基础齿轮油分别减小了37.8%和30.2%;含纳米金属/蛇纹石粉的齿轮油具有更好的综合摩擦学性能,且具有良好的载荷特性,当纳米镍粉与铜粉的质量比为3∶1、金属粉体与蛇纹石粉的质量比为2∶1、粉体总加入量(w)为0.2%时,试验摩擦因数和磨斑直径比基础齿轮油分别减小了37.4%和34.0%;钢球磨痕形貌及能谱分析结果表明,纳米金属、蛇纹石粉体加入到齿轮油中能起到填平犁沟、修复磨痕表面的作用。using four-ball tester and EDS technique. Experimental results indicate that the gear oils with nano-Ni/ Cu composite powder achieve a better triboligical behavior than the one with single powder. The friction coefficient and wear scar diameter decreased by 37.8% and 30.2% respectively when the amount of nano-Ni/Cu composite powder （mass ratio of Ni and Cu of 3 ： 1） added is 0. 1%. The gear oils containing nano-metal/serpentine composite powder has even better tribological properties and good load char-acteristics. The friction coefficient and wear scar diameter decreased by 37.4% and 34.0%, respectively when the dosage of the metal/serpentine composite powder is 0.2% with the mass ratio of metal powder （Ni and Cu ratio of 3 ： 1） and serpentine of 2 ： 1, and. The wear scar morphology and the EDS analysis show that the nano-metal/serpentine composite powder could fill the furrows and repair the worn surface.
