摘　　要：利用高温摩擦磨损试验机考察了BMI基耐高温固体润滑膜在不同环境温度下大气中的摩擦学性能,并采用DSC,SEM以及XPS等分析手段对其磨损机理进行了研究。试验结果表明,该膜在室温到250℃温度范围内可长期使用,具有优异的摩擦学性能,在常温下润滑膜的转移不好,而在200℃时可形成完整的转移膜。The tribological properties of the bonded solid lubrication coatings as modified bismaleimide matrix with high temperature resistance were examined using a pin disk tester under different temperature in air The tribological test results demonstrate that the coating not only has good tribological property but also can be used for a long time in the range of room temperature to 250℃ DSC, SEM and XPS had been utilized to explore the wear mechanisms Analyses of worn surface indicates that the transfer of lubricating film is not good under the ambient temperature whereas it is easy to form the complete transfer film under 200℃
