摘　　要：在连续加载条件下,考察了纳米Al2O3/FeS固体润滑复合层在不同温度时的减摩抗磨性能;利用X射线光电子能谱(XPS)分析了不同温度下磨损表面所含元素及其化学价态.结果表明:纳米Al2O3/FeS固体润滑复合层在室温至150℃范围内,具有优异的减摩性能和抗磨性能;磨损表面存在S元素,并以硫化物和硫酸盐形式存在,但未发现Al元素,表明磨损表面形成了主要由硫化物和硫酸盐组成的摩擦化学反应膜.The friction reducing and anti-wear properties of the nano-Al2O3/FeS solid lubricant composite layer were investigated using a MS-T4000 tester under a continuous loading at elevated temperature.The chemical states of typical elements on the worn surfaces were analyzed using X-ray Photoelectron Spectroscopy（XPS）.The results showed that nano-Al2O3/FeS solid lubricant composite layer possessed excellent friction reducing properties and wear resistance from room temperature to 150 ℃ under a continuous loading.Element S in forms of sulfide and sulfate was found on the worn surface while element Al was not found.This suggested that the tribochemical film on the worn surface were mainly sulfide and sulfate.
