摘要：

In present paper, the influence of copper on wear-friction behaviour of hypereutectic Al-Si alloy (Al-18% Si-0.5% Mg) has been investigated. Sliding tests were conducted under dry sliding conditions against hardened steel En-31 counter surface over a range of sliding speed from 2.0 to 7.0 m/s and contact load from 10 to 80 N. It was observed that the wear rate is a function of contact load, sliding speed, composition and thermal softening characteristics of sliding metal. Wear of hypereutectic aluminium-silicon alloy is not appreciably affected with the addition of copper. However, addition of copper increases the transition load at 2.0 m/s sliding speed. Copper addition more than 2%, did not show any effect on the transition load. (C) 2004 Elsevier B.V. All rights reserved.
