Experimental Investigation on Wear Behaviour of AA6082 Aluminium Alloy, Tungsten Carbide and Graphite Hybrid Composites

Abstract

In this experimental study, Aluminium alloy (AA) 6082 was strengthened with Tungsten Carbide and graphite through stir casting technique. Scanning Electron Microscope (SEM) was employed to study the wear performance of the Al/WC/Gr composites. Wear tests were carried out using a pin-ondisc apparatus. The input parameters in this study are the load applied (4, 8, 12, 16, and 20 kg), speed of sliding (1, 1.5, 2, 2.5 and 3 m/s) and distance slides (1000, 1500, 2000 and 2500 m). Response Surface Methodology (RSM) has been carried the use of MINITAB 14 software program to examine the rate of wear and frictional behaviour of the hybrid composites.
