| 摘 要： | 采用机械化学法制备了纳米铜/蛇纹石复合润滑材料,利用微动摩擦磨损试验机考察了其作为润滑油添加剂的摩擦学性能,借助纳米压痕仪（nano-in-denter）、扫描电子显微镜（SEM）、能量色散谱仪（EDS）及光电子能谱仪（XPS）对磨损表面进行了表征,探讨了减摩抗磨机理。结果表明复合润滑材料具有优异的摩擦学性能,其摩擦因数及磨损率分别较基础油降低约16.4%和69.2%。复合润滑剂颗粒参与了摩擦界面复杂的理化作用,形成了致密光滑的保护膜,主要由Fe、Si等元素组成,具有较高的微观力学性能,提高了摩擦表面的磨损抗力,显著地降低了摩擦磨损。

| Abstract: | A copper nanoparticles/serpentine composite as lubricating material was prepared using mechano-chemical method.The tribological properties of the as-prepared material as oil additive were evaluated by employing an oscillating friction and wear tester.The worn surface was characterized by means of nano-indenter,scanning electron microscopy(SEM) equipped with energy dispersive spectroscopy(EDS) and X-ray photoelectron spectrometer(XPS).The mechanism for the friction and wear reducing properties was discussed.... |
