Statistical Approach to Sliding Wear of Ceramic Reinforced Metal Matrix Composite/Metal Systems

研究了铝-碳化硅金属基复合材料与淬硬钢的摩擦磨损行为。复合材料和钢对偶面的磨损行为将被确定，并与显微组织有关。结果将用于验证将要开发的磨损率统计模型。该模型将基于硬颗粒在铝基中随机聚集的理论，并假设钢的磨损本质上是磨料磨损，是由复合材料中的硬质相引起的。

The tribological behavior of Al-SiC metal matrix composites sliding against hardened steel will be studied. The wear behavior of the composites and of the steel counterface will be determined and related to microstructure. The results will be used to validate a statistical model to be developed for the wear rate. The model will be based on a theory of random clumping of the hard particles in the aluminum matrix and on the assumption that the wear of the steel is abrasive in nature and caused by the hard phase in the composite.
