摘　　要：采用放电等离子烧结法制备了铜基自润滑复合材料(C13W),在海水及空气中对C13W与对比材料铝青铜(AlCu)进行摩擦磨损试验;通过腐蚀磨损形貌、摩擦因数及磨损率,对比分析了铜基自润滑复合材料和铝青铜在海水环境中的耐腐蚀磨损性能。结果表明:与空气中相比,铜基自润滑复合材料在海水中的耐蚀性能更佳,且其摩擦因数及磨损率都比铝青铜优异,更适合在海洋环境中的应用。The copper based self-lubricating composite(C13W)was prepared by spark plasma sintering method.Friction and wear tests were conducted in seawater and air on the C13W,and aluminum bronze(AlCu)was used as contrast material.The corrosion and wear resistance of copper based self-lubricating composite in seawater was analyzed in comparison with aluminum bronze through corrosion and wear morphology,friction coefficient and wear rate.The results show that the corrosion resistance of copper based self-lubricating composite in seawater was better than that in air.The friction coefficient and wear rate of the C13W were superior to aluminum bronze.So the C13W is more suitable for application in marine environment.
