摘要
本文研究了粗颗粒氧化铝陶瓷基复合材料在无润滑条件下不同载荷时的耐磨性能 ,并对其磨损机理进行了探讨。试验结果表明 ,该材料对外加载荷具有较大的敏感性。通过对磨痕形貌的观察研究 ,认为该材料的磨损机理是以脆性剥落和磨粒磨损为主 。
The wear resistance behaviors of coarse alumina ceramic matrix composite(CMC)have been studied under different loads without oil lubrication Results shown that the wear behavior of the material is sensitive to the loading level by lack of oil lubrication It is proposed that the wear modes of the material,when runs without oil lubrication,are mainly the brittle peeling off and abrasive wear,accompanying with some fatigue wear
