Abstract
TiC particles are reinforced with Al 7075 to develop metal matrix composite. Special purpose die is fabricated for centrifugal casting machine for the preparation of composite material. The tribological properties such as wear rate and coefficient of friction are determined by using pin on disc wear testing machine. Weight percentage of TiC, applied load, sliding distance are considered as parameters for the wear test. The results show that the wear resistance of the developed composite increases with increase of TiC percentage. Wear rate of Al-TiC composite is observed to be reduced by 11%, 31% and 42% with increasing percentage of TiC by 2.5%, 5% and 7.5% respectively. SEM and EDS analysis are used for morphological study of the worn surfaces of composite. Keywords: Composites, Al-TiC, Wear, Coefficient of Friction (CoF), SEM
