An Experimental Inquire on Dry Sliding Wear Behaviour of Al-Si-Mg-Cu-SiC Composites Fabricated by Metallurgical Powder Technique

Abstract

At present, material properties are being continuously improved in line with current technological developments to meet operational and safety standards. Designers and consumers now look for materials that are more energy-efficient, stronger, lighter, as well as cheaper. A metal-matrix composite (MMCs) represents a dominant class of material which can be suitably designed to meet the above requirements. With a variety of reinforcing materials and flexibility in their preliminary processing, Aluminum Metal-Matrix Composites (AMMCs) offer great potential for developing composites with desired properties for larger applications. In this research, a novel composite has been fabricated with Silicon, Magnesium, Copper, Silicon Carbide, and Aluminium with 0.5, 0.5, 2.5, 15, and 81.5 percent respectively by weight using the metallurgical powder technique. The composite has been studied and investigated its wear behavior in dry sliding mode and found that the wear-rate increases with load applied as well as with sliding-speed and decreases with an increase in the percent of SiC content in the composites.
