【摘要】 选用合成极压蜗杆油、未加油性剂和极压剂的半成品蜗杆油作为基础试验油 ,将超微金刚石粉、纳米铁粒子和纳米铜粒子分别以两种不同质量比分散到半成品蜗杆油中。在 MM-2 0 0型磨损实验机上 ,考察纳米粒子的抗磨减摩性 ,并与传统的油性剂、极压剂进行比较。同时探索应用于钢 /钢副硬齿面的新型抗磨减摩添加剂。试验结果发现 :平均粒径尺寸为 5 nm的超微金刚石粉具有优于传统油性剂、极压剂的抗磨减摩性能 ,可以大大降低钢 /钢副的摩擦 ,减小磨损。但钢 /钢副中不宜使用含有纳米铁粒子的润滑油。更多还原

【Abstract】 In this paper,the ultrafine diamond powder,Fe nano particles and Cu nano particles are used as an additive to be dispersed in the worm oils of synthesized intermediate product respectively.The performance of nano particales antiwear and anti reducing is compared with traditional oiliness improver and extreme pressure lubricant.The test is also done to probe and develop new materials that can be applied to such tough steel/steel friction pairs.The result shows that ultrafine diamond powder has excellent the antiwear and anti friction reducing performance,it can lower greatly the friction and reduce the wear of the steel/steel pair,but Fe nano particles can not be used.更多还原
