Wear Properties of Alumina Particles Reinforced Aluminium Alloy Matrix Composite

Faiz Ahmad, M. Rafi Raza, A. Majdi Ab. Rani and S.H. Jason Lo

Abstract:
In this study results of wear and friction coefficient of alumina particles reinforced Aluminium Matrix Composite (AMCs) were presented. The wear of AMCs was tested against the brake pad material under various loads ranging from 50 to 200 N at fixed speed of 600 rpm. A pin on-disk apparatus was used for measurement of wear rate of AMCs and resulting microstructure at each load was examined under scanning electron microscope. The coefficient of friction was also measured for corresponding loading conditions studied. Results showed an increased wear rate of AMCs with increased load and decrease in friction coefficient. Micro structural analysis of AMCs showed a combination of adhesive and abrasive types of wear for sample tested at loads. The reduction in coefficient of friction was noted as the surface of AMCs became rougher tested at higher load. This was related to the removal of alumina particles from the surface of AMCs during wear test at higher load that rough reduced coefficient of friction.
