| Abstract | ||
| In This study metal matrix composite (MMCs) was produced by using aluminum as base metal matrix reinforced with the SiC particulates using conventional casting technique, macro structural studies showed that uniform distribution of SiC particulates. The density of MMCs decreased with the increase in SiC wt%. The Hardness of MMCs increased with the increase in SiC wt%, composites exhibit a significant acceleration in kinetics of preciptation in compare with the unreinforced matrix alloy. A pin on disc wear testing machine was used to evaluated the wear loss of composites. The results showed that wear rates of composites are lower than of the matrix alloy and further decrease with increase in SiC particulate content. | ||
