Özet

Aluminium bronze is one of the versatile wear resisting engineering materials that work under a corrosive environment with high stress. Alloys were produced by casting of C95200 and C95300 aluminium bronzes and aged. Wear behaviors, friction coefficient, and microstructure were investigated. The results indicated that a suitable aging treatment resulted in the formation of smaller alpha grains than their cast condition. These small alpha grains could improve the hardness and wear resistance of Cu-Al-Fe alloys. But with increasing aging temperature, the wear rate of the aged Cu-Al-Fe alloys initially decreased and then began to increase. (C) 2008 Elsevier Ltd. All rights reserved.
