摘要：
Purpose - The purpose of the paper is to study the dry sliding wear behavior of as-cast and heat-treated zinc-aluminum (ZA-27) alloy, reinforced with silicon carbide and graphite particles. Design/methodology/approach - The alloy and composite samples were prepared with stir casting technique. Heat treatment was carried out for samples at a temperature of 370 degrees C followed by quenching in water at room temperature. Subsequently, the heat-treated samples were aged at 180 degrees C and quenched in water at room temperature. The wear tests were carried using pin-on-disc apparatus at room temperature at different applied loads, sliding speed and sliding distance. Findings - The wear volume loss of as-cast samples was more compared with heat treated samples. Composites exhibited improved wear resistance than base alloy. Originality/value - Hybrid metal matrix composites with heat treatment has exhibited superior wear behavior in dry sliding conditions.
