In this study, wear behaviors of aluminum alloy matrix 50 vol. % SiC particulate reinforced composites were investigated. Composites were produced by squeeze casting technique by utilizing 2618, 7012 and 7075 aluminum alloys as the matrix and abrasive grade green 30 μm SiC particles as the reinforcement. Wear tests were conducted in dry air and in water by rubbing Al 2O3 balls on the surfaces of composites on a reciprocating wear tester. Wear tests were carried out at the mean contact pressure of 0.6 GPa in dry air conditions and at 2.4 GPa in water. The results of the wear tests revealed that, in dry air sliding conditions, where wear progresses by removal of SiCp's from contact surface, wear resistance is strongly related to the hardness. Even if the mean contact pressure is four fold higher than in dry air sliding wear, SiCp's remain on the contact surface and composites exhibit considerably high wear resistance and noticeably low fiction coefficient in water.
