该文对SiC颗粒增强的钢基复合材料在油润滑条件下的快速磨损试验进行研究.结果表明,添加SiC硬质颗粒材料的耐磨性能得到明显提高.同时该文初步探讨了SiC颗粒增强复合材料的耐磨机理.“,”In this paper the rapid wear test of steel matrix PM composite reinforced with SiCp has been studied. The results have pointed out that the composite reinforced with SiCp can greatly improve wear resistance. We have also discussed the wear resisting mechanisms of composite.
