Abstract

The in-situ method of making Zinc-aluminium composites wherein TiC has been introduced has been investigated in the present paper for its microstructural, physical and dry sliding wear behaviour and compared with the base alloy. In the present study ZA-27 alloy reinforced with 5 & 10 volume percent TiC was taken into consideration. The results indicate that the wear rate & coefficient of friction of composites was lower than that of base alloy. The material loss in terms of both wear volume loss and wear rate increases with increase in load and sliding distance respectively while coefficient of friction follows a reverse trend with increase in load. Better performance was obtained for 5% TiC reinforcement than with 10% probably due to agglomeration of particles resulting in non-unifform dispersion. Worn surfaces were analyzed by electron microscopy (SEM) analysis.
