Abstract

In this research, the effect of applied load on sliding wear characteristics of as-cast and heat treated ZK60 Mg alloy was investigated. The as-cast alloy was homogenized at 450°C and aged at 170°C for 10 and 35 h. The dry sliding wear behavior of the as-cast and heat treated alloys was investigated using a pin-on-disk wear test under various loads in the range of 10-160 N at a sliding velocity of 0.1 m/s for 1000 m. The worn surfaces were evaluated using scanning electron microscopy equipped with energy dispersive spectroscopy analysis. The results confirmed that the wear mechanism was dependent on the applied load. Findings revealed that the most dominant wear mechanisms under low, intermediate and high loads were oxidation, abrasion/adhesion and delamination, respectively. The heat-treated and as-cast alloys showed almost similar wear resistance under low loads, however, the heat-treated alloys showed better wear resistance than the as-cast ones at high loads.
