纳米铜润滑油添加剂的制备及其性能研究

Research on the Preparation and Properties of Cu Nanoparticles Lubricant Addictive

采用KBH4液相还原法制备了具有面心立方结构，粒径约为40nm的纳米铜颗粒。利用环块摩擦磨损试验机考察了其作为添加剂在不同润滑油中的摩擦学性能，利用SEM、EDS等对摩擦表面进行了形貌、成分分析，探讨了纳米铜颗粒作为添加剂的作用机理。

By reducing CuSO4 with KBH4 , FCC Cu nanoparticles, with an average size of 40 nm, are prepared in the present work. Ring-on-block tester is employed to investigate the tribological properties of Cu nanoparticles as additive in different lubricants. The morphologies of the worn surfaces and element distributions are analyzed with SEM and EDS, and the tribological mechanism of Cu nanoparticles is discussed.
