摘要:
采用化学反应法制备了5种纳米铜微粉，采用超声分散工艺分散于400SN基础油中进行摩擦磨损试验。试验结果表明，在试验范围内1#、2#和3#纳米铜在较高载荷下能够提高基础油的抗磨性能，磨斑直径为基础油润滑时的70%。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形成了保护性润滑膜，起到改善润滑油抗磨性能的作用。

Abstract:
Five kinds of copper nanometer particles were synthesized with chemical reaction method and dispersed in 400SN lubricant oil by means of ultrasonic disperse process. The effect of the nano-Cu particles as an additive on the anti-wear ability of 400SN oil was examined on a four-ball machine. The results showed that the 1#, 2# and 3# nano-Cu additives could considerably increase the anti-wear ability of base oil under higher load in test. The element dispersing on the worn surfaces were studied by means of electron microprobe analysis. Cu element was observed obviously. The deposition of nano-Cu on the worn surface contributed to the improvement of the anti-wear ability.
