【摘要】 利用T-11摩擦磨损试验机和MM-200摩擦磨损试验机进行了用纳米铜添加剂润滑的摩擦磨损试验,在磨痕表面形成了富含Cu元素的表面膜。纳米压痕试验结果表明,基体的硬度为10~12GPa,而表面自修复膜的硬度从5GPa到10GPa,变化范围比较大。从硬度以及加工硬化程度和蠕变位移的测试结果可以看出,摩擦表面自修复膜的这些性能与纯铜膜的性能有很大的区别,而且在不同的深度有不同的变化,说明薄膜不是均匀铜膜,而是在成分、组织结构上有变化的复合膜。更多还原

【Abstract】 The wear test was carried out on a T-11 ball-on-plate friction and wear tester and MM-200 friction and wear tester.A film mainly made of Cu was formed on the worn surface.Nano-indentation tests indicated that the copper film formed by Cu nano-particles additives has a lower hardness compared with that of the base material.The hardness of base materials varied from 10 GPa to 12 GPa,while the hardness of the self-repairing film was varied from 5GPa to 10 GPa.Results showed that the hardness,work hardening and creep displacement values of the self-repairing film were markedly different from that of the pure Cu film and varied with depth.This tells that the self-repairing film is a composite film of varying composition and structure rather than a homogeneous Cu film.更多还原
