【摘要】 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更多还原

【Abstract】 This paper dealt with the sliding wear behavior of the SiCp reinforced aluminum matrix composites made by agitation casting method. The wear resistance of MMCs under dry sliding and lubricated sliding conditions was analysed carefully when the loading level was varied, the factors effecting the sliding behavior of MMCs were also discussed. The results show that the wear resistance of MMCs is better than that of base material regardless of the dry sliding or the lubricated sliding case, which is more conspicuous especially under high loading level.更多还原
