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、镍铜粉复配剂和纳米金属粉与超细蛇纹石粉复配剂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、铜粉复配剂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，摩擦系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，摩擦系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。

Abstract:

To improve the tribological properties of conventional gear oils, the affects of amounts and mass ratios of nano-Ni、nano-Ni/Cu composite powders and nano-metal/serpentine composite powders on tribological properties of gear oils had been studied by using four-ball tester, and studied its load characteristics. Experimental results indicated that the gear oils which had been added nano-Ni/Cu composite powders could achieve a better triboligical behavior than the one that had been added single powders, the friction coefficient and wear scar diameter decreased 37.8% and 30.2% , when the mass ratio of Ni and Cu was 3:1, and the total amount was 0.1%; The gear oils containing nano-metal/serpentine composite powders had better tribological properties in all aspects, and had a good load characteristics and self-repairing properties, the friction coefficient and wear scar diameter decreased 37.4% and 34.0% , when the mass ratio of Ni and Cu was 3:1, the mass ratio of metal and serpentine was 2:1, and the total amount was 0.2%. Wear scar morphology and EDS analysis showed that the nano-metal/serpentine composite powders added to the gear oil could fill a fill furrows and repair worn surface.
