Abstract: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.
