Abstract

In this paper, an attempt has been made for the use of waste fly ash cenosphere for tribological wear behaviour. LM6/cenosphere composites were fabricated by stir casting method. An experimental study has been conducted on pin-on-disc wear testing machine to determine the abrasive wear behaviour of cenosphere particulate-reinforced metal matrix composite. Studies were done by varying the load (5, 10, 15, and 20 N) on 5%, and 7.5, 10, and 12.5% weight percentages of reinforcement at a velocity of 1.0472 m/s. The results revealed that the wear resistance of the 10 wt% reinforced composites is superior to that of other reinforced and unreinforced composites. The worn surface morphology of the eroded surfaces wear was examined using scanning electron microscopy (SEM). The SEM analysis reveals the presence of both abrasive wear and delamination wear mechanism.
