Abstract
The abrasive wear properties of stir-cast LM6 aluminum alloy-10 wt. % cenosphere composite were tested against hard SiC abrasive paper with different grit sizes and compared with the LM6 aluminum alloy. The results show that the abrasive wear resistance of LM6/cenosphere composite is better than the LM6 aluminum alloy for low loads up to 15 N (transition load) on a pin sample. The SWR and coefficient of friction decreases with increasing load. SEM studies reveal the presence of both abrasive and adhesive wear mechanisms and from both the mechanism the abrasive wear mechanism is more prominent and dominating.
