Effect of applied pressure on the tribological behaviour of SiCp reinforced AA2024 alloy

Abstract

Effect of applied pressure on the tribological behaviour of SiCp reinforced aluminium alloy was investigated under varying applied pressure (0.2–1.8 MPa) and a sliding speed of 3.35 m/s, giving emphasis on the parameters such as coefficient of friction, temperature and wear rate as a function of applied pressure. The overall results indicated that dispersion of 10 wt% SiCp to the base alloy made the seizure resistance to improved by 33%, similarly 25 wt% SiCp, the seizure resistance enhanced by 50%. Understanding the mechanism of material removal and formation of mechanically mixed layer by EDX analysis through developed wear tracks.
