Abstract

Tribological properties including lubricated friction and wear of Zn-25Al-3Cu-1Si alloy were investigated using a block-on-disc type wear test machine. The results obtained from the alloy were compared with those of SAE 660 bearing bronze. It was observed that the T6 heat treatment increased the hardness, strength and wear resistance of the alloy. As the contact pressure increased friction coefficient of the alloy and the bronze decreased, but their working temperature and wear volume increased. Zn-25Al-3Cu-1Si alloy in both conditions was found to be much superior to SAE 660 bronze as far as their mechanical and tribological properties are concerned. (C) 2014 Elsevier Ltd.
