摘要:
采用KBH4液相还原法制备了纳米铜颗粒,通过X射线衍射和透射电镜分析,得出所制备的纳米铜颗粒的粒径约为20nm的圆球形颗粒。分析了表面修饰的纳米铜颗粒作为润滑油添加剂的摩擦学性能和作用机理,结果表明纳米铜的加入,能在磨损表面形成一层润滑性的铜膜,从而能够有效地改善润滑油的抗磨减摩性能,降低润滑油的摩擦因数,减小摩擦副的磨损量,并得出纳米铜添加剂的最佳用量。

Abstract:
The preparation of Cu nanoparticles using KBH4 liquid phase reducing method was investigated.The results of XRD and TEM analyses indicated that the prepared Cu shows circular nanoparticles with grain size of 20 nm.As lubricating oil additive,the tribological properties and function mechanism of Cu nanoparticles were studied,the addition of nano-Cu could improve anti-wear and friction reducing properties of lubricating oil,reduce friction coefficient and decrease wear extent.Finally the concentration of nano-Cu was optimized.
Key words:  Cu nano-additive  tribological properties  anti-wear and friction reducing
