摘要
采用粉末冶金方法制备了Cu-Sn10-Pb10减摩复合材料,并对其在室温至500℃环境温度条件下进行了摩擦磨损特性研究。结果表明,材料摩擦表面随着试验温度的升高磨损加剧,400℃时材料基体发生严重变形,形成塌陷和凹坑;温度升高使材料润滑膜破坏,氧化加剧,进而铜基体直接参与摩擦且被氧化几率增加,材料磨损程度加剧。
The Cu - Sn10 - Pb10 anti - friction composite materials were made by conventional powder metallurgy method. This thesis analyzed the friction and wear properties of them from room temperature to 500℃. The results show that the wear of the composites increased with the increase of the testing temperature. The matrix of composite materials heavily deformed forming collapses and dents. Peeling off and oxidation of lubricating film made the probability of copper matrix participated in friction directly and oxidation increased, materials attrition rate prick up, with the increase of the testing temperature.
