MATERIALS & DESIGN

In this study, Al based Al2O3 and SiC particle reinforced composite materials were manufactured by casting or P/M method. Tribological properties of these composite materials were investigated by wearing with 10 N load and 50 rpm on a pin-on-disc wear test rig at dry conditions. Mechanical properties were investigated. The effects of reinforce materials on tribological and mechanical properties were investigated. In addition to that microstructure of these materials were investigated by optical and SEMI microscope. Tribological and hardness properties of composites significantly improved by the use of particle reinforced into Al. (C) 2008 Published by Elsevier Ltd
