Abstract
The friction and wear behavior of 2024 aluminum alloy reinforced with 15 vol.% SiC whiskers against 52100 steel was investigated in a oscillating sliding wear tester at ambient condition. The Al-SiC composites exhibited better wear resistance than the 2024-Al alloy under the same test conditions. With increasing load, the Al-SiC composites exhibited high friction coefficient. The debris of steel/Al alloy pair was mainly aluminum oxide, while the debris of steel/Al-SiC composite pair was mainly ferrite oxide. The predominant wear mechanisms of Al-SiC composites are delamination and adhesion at low load, ploughing and oxidation at high load.
