| 摘 要： | 采用UMT-2型球-盘摩擦磨损试验机研究溅射沉积MoS2/Sb2O3复合固体润滑膜的滑动摩擦磨损寿命,采用显微镜分析球-盘摩擦副在不同磨损阶段的磨损形貌与磨损状况,并对磨痕位置S、Mo元素进行XPS分析。结果表明:在摩擦磨损寿命试验过程中,摩擦副的接触方式最开始的点接触逐步过渡到面接触;MoS2固体润滑膜对滑动摩擦副的延寿作用是基底材料表面的有效厚度润滑膜及MoS2对摩擦偶件(钢球)的转移;机械磨损的剪切剥离效应是润滑失效的主要原因,MoS2的氧化在一定程度上加剧了润滑失效的进程。

| Abstract: | The MoS2/Sb2O3 composite films fabricated on the 9Cr18 steel discs were investigated by means of a tribometer.The worn surface morphologies of balls and discs during different worn phases were measured on a high resolution microscope.The main chemical elements S,Mo in the worn surface were analyzed with PHI-5720 XPS.The worn areas of discs during different worn phases were measured with the aid of a nano scratch meter.The results show that the MoS2/Sb2O3 composite films have better oxidation resistance prop... |
