Abstract

In this research, stir casting technique was employed for composite fabrication. AA6082 alloy alongside Al2O3 particles with 5% weight and nano-SiC(n-SiC) particles with weight percentage of 0%, 3%, 6% and 9%were used as the constituent materials. Effects of n-SiC were investigated on the hardness, tensile strength and dry sliding wear behaviour of AA6082/5 wt.% Al2O3/ x wt.% n-SiC (x = 0, 3, 6 and 9) hybrid composites. Speed of 1 m/s and normal load of 10 N and 30 N are used for experimental trials. The sliding distance was kept as 3,200 m and the rotational velocity was kept as 400 rpm for the whole test run. The result demonstrates significant improvements in tensile strength and hardness of the hybrid composites. It was found that the wear decreases with the addition of SiC, whereas the normal load contributes in higher loss of material. Furthermore, SEM analysis shows the presence of abrasion and delamination wear in the hybrid composites.
