Evaluating the Effect of Different Percentage Addition of SiC on Mechanical and Wear Properties of Al6061 Composite

Abstract

AbstractAluminum 6061 alloy using silicon carbide (SiC) particles as a reinforcement is a promising metal matrix composite (MMC) that has gained significant attention in the automotive and aerospace industries. Till now the effect of the addition of SiC particles in Al6061 composite is not studied in depth and also very few studies are reported the on‐wear properties of Al6061‐SiC composite. So, to further enhance the properties of Al6061 alloy and to study in depth this work is carried out. In this study, MMCs are prepared using the stir casting route with varying weight fractions (5–10 wt%) of SiC particles. The properties of composites including tensile strength, compression strength, and wear are evaluated experimentally. The results demonstrated that the incorporation of SiC particles into the Al alloy matrix leads to a notable improvement in mechanical and wear parameters. The tensile and compression strength of the Al composites increases with an increase in the weight percentage addition of SiC particles (from 5% to 7.5%). At 7.5 wt% addition of SiC, it is found that the particles are uniformly distributed throughout the Al6061 alloy matrix. And also shows higher mechanical and wear properties as compared to 5% and 10% addition.
