Abstract

The present study investigates on the two body abrasive wear behavior of Al-6082 alloy, Al 6082 alloy-10% SiC (Al-SiC) composites and Al 6082 alloy5 % SiC-5 % Gr (Al-SiC-Gr) hybrid composites. These composites were prepared by stir casting process. The wear tests of these materials were conducted at load of 515 N and sliding distance of 5075 m at grit size of 200 µm. The wear response influenced by these parameters was analyzed and compared with each other. The results show that graphitic composites yielded better wear resistance compared to alloy and single SiC reinforced composite. Worn surfaces of samples were observed by using scanning electron microscope (SEM) and it was revealed that the wear grooves appeared to be narrow and shallow in case of hybrid composites.
