Due to their excellent strength to weight ratio, aluminum alloys are widely used in a variety of automotive components. Their relatively low melting point and low hardness compared to other engineering alloys, however, limits their use in applications where wear resistance is needed. To improve the wear resistance of these alloys, a good understanding of their wear behavior is essential. Dry sliding wear behavior of A380M aluminum alloy was investigated in the load range 6-20 N against steel ball using a reciprocating ball-on-flat configuration and at a frequency range of 4-20 Hz. Micromechanical properties were measured using a nano-indentation system. Scanning electron microscope examination of the wear track and debris revealed that wear within the present load and frequency range was due to abrasion, plastic deformation, and delamination. It was found that the wear rate of A380M aluminum alloy increased with load and decreased with increase in frequency.
