摘　　要：以Cu-Al为基添加适量的Ni、Fe、Mn在金属型模具中铸造一种多元铝青铜合金Cu-12Al-X,利用扫描电镜、UMT-2摩擦磨损仪研究Cu-12Al-X合金的摩擦磨损行为,并以合金ZCuAl10Fe3作为对比材料进行分析。结果表明:Cu-12Al-X合金的耐磨性显著优于ZCuAl10Fe3合金的,且经过固溶时效后(950℃,2 h,固溶)+(550℃,4 h,时效),Cu-12Al-X合金在常温、高温环境下的摩擦因数及磨损量均低于铸态合金的,具有良好的耐磨性能。A wear resistant aluminum-bronze alloy Cu-12Al-X was prepared by adding some elements （Ni, Fe, Mn） based on the Cu-Al alloy, then was produced by casting. Wear-friction behavior of aluminum bronze Cu-12Al-X was studied with making use of SEM, UMT-2 friction and wear tester, and use ZCuAl10Fe3 alloy as the contrast material. The results show that the wear-friction behavior of Cu-12Al-X alloy is higher than that of ZCuAl10Fe3 alloy, and the friction factor and wear loss of Cu-12Al-X alloy under the conditions of solution at 950℃for 2 h and aging at 550℃for 4 h are lower than the that of as-cast alloy, the alloy in this state has good wear resistant.
