This work investigated the influence of fly ash and sic on the wear behavior of Al 7072,5 and 10 wt. % of hybrid
composites. Research reveals the effectiveness of incorporating Sic into the compound to obtain reduced wear. The Al 7072
reinforced with sic-fly ash were investigated. The composites were fabricated using the under-stir casting route. Ceramic
particles along with solid lubricating materials were incorporated into an aluminum alloy matrix to accomplish a reduction in
both wear resistance and enhance the coefficient of friction. The Al 7072/fly ash/sic hybrid composite was prepared with 5,and
10 wt. % of sic /fly ash particles. It was observed the stress on pin in composites was good compared to the matrix alloy. And it
was evident from the SEM microstructures that no particle was cracked or pulled out from the matrix. This was due to a good
interfacial bond between the alloy and the matrix. These findings suggest that a hybrid composite system gives better wearresistant properties.
