摘　　要：采用化学反应法制备了表面修饰的纳米铜微粉，采用超声分散工艺分散于16#机油基础油中，利用T-11摩擦磨损实验机进行摩擦磨损试验。试验结果表明：不含纳米Cu的减摩添加剂和含纳米Cu的减摩添加剂添加到16#机油中，磨损量分别减少了19％、33％，减摩性能分别提高59％、86％。能谱分析表明磨痕表面不均匀的分布有铜元素，说明添加剂中的纳米铜在磨痕表面沉积，起到改善润滑油抗磨性能的作用。The surface modified nanocopper particles were prepared with chemical reduction method and dispersed in 16 ;~ lubricant oil of tank by means of ultrasonic disperse process. By the use of T-- 11 friction and wear test machine, tribology properties of the lubricants with different additives were obtained. The results showed that lubricants containing nanoparticles has a good anti--wear and antifriction properties. Compared with the base oil, the anti--wear ablity had been advanced by 19% without nano--Cu and 33% with nano--Cu, the friction ablity had been advaced by 59% without nano--Cu and 86% with nano--Cu. The elemental distributions on the worn surfaces were determined by means of electron microprobe analysis. There was Cu element observed obviously. The deposition of nano--Cu on the worn surface contributed to the increased of the anti--wear ability.
