摘　　要：用SEM、XRD观察真空烧结材料的组织形貌,用MM200磨损试验机检测了VC铁基复合材料的耐磨性,分析了VC铁基复合材料的磨损机理。结果表明,复合材料具有良好的耐磨性能,且VC颗粒分布均匀,与基体结合良好。SEM and XRD were used to observed the microstructure morphology of vacuum sintered composite.The wear-resistance of VC-iron matrix composite was examined on a MM-200 wear-test machine. The wear mechanism of the composite was analyzed.The results show that the composite has the excellent wear-resistance,and VC grain is uniform distributiom and has the good combination with the matrix.
