研究了用搅拌铸造法制备的ＳｉＣ颗粒增强铝基复合材料的滑动磨损行为。对载荷改变时，复合材料在干摩擦和油润滑条件下的耐磨性进行了较细致的分析，并对影响该复合材料滑动磨损行为的因素进行了讨论。结果表明：无论在干摩擦还是油润滑条件下，复合材料均比基体耐磨，但在油润滑条件下，尤其是高载时，复合材料的耐磨性能更突出地显示出来 The sliding wear behavior of SiC particle reinforced aluminum matrix composites prepared by stirring casting method was studied. When the load changes, the wear resistance of the composite under dry friction and oil lubrication conditions is analyzed in detail, and the factors affecting the sliding wear behavior of the composite are discussed. The results show that the composite material is more wear-resistant than the matrix in either dry or oil-lubricated condition, but the wear resistance of the composite material is more prominent under oil-lubricated conditions, especially at high load
