Abstract: This paper investigates the effects of contact pressure, sliding speed and alloy condition on dry sliding wear behaviour of LM13 (AI-12Si-0.8Cu-1̇0Ni- 0̇6Mg) alloy. A pin on disc type wear testing machine was used to study the wear behaviour of alloy in untreated, melt and heat treated condition. Dry sliding wear tests were performed at two contact pressures (0̇31 and 0̇93 MPa) and four sliding speeds (0̇2, 0̇5, 0̇9 and 2̇0 m s-1). The wear rate decreased with the increase in sliding speed irrespective of contact pressure and alloy condition used in this work. The untreated alloy exhibited higher wear rate than melt and heat treated alloy. The refinement of eutectic Si by melt treatment and spheroidisation of eutectic Si after heat treatment of LM13 alloy have been attributed to the reduction in wear. Melt treatment and heat treatment of LM13 alloy increased the hardness and tensile strength, while increase in ductility was marginal. © 2008 W.S Maney & Son Ltd.
