Tribological Analysis of Aluminium-Based MMC Reinforced with Silicon Carbide & Magnesium

Metal matrix composite (MMCs) can have a much higher strength-to-weight ratio, firmness, and ductility than conventional materials, so they are regularly used in various applications. This study includes tribological examination of aluminium, magnesium (Mg), and silicon carbide (SiC) reinforced MMC. Utilizing powder metallurgy and hot pressing, the composite was synthesized. Wear resistance and friction behaviour are two examples of tribological features that were thoroughly studied. According to the microstructural characterisation, SiC and Mg particles were distributed uniformly throughout the aluminium matrix, which improved the material’s mechanical strength and wear resistance. Tribological studies were performed with a pin-on-disc device at different sliding speeds and loads to determine how these factors affect wear and friction performance. The effect of process variables is also investigated. The outcomes showed that the wear rate and friction coefficient were significantly reduced by adding SiC and Mg. The three input parameters used for compression are 300 MPa, 350 MPa, and 400 MPa. The three-level composition is also used for SiC and Mg as 3%, 6%, and 9%. The SEM analysis shows a uniform distribution of the Mg and SiC particles in the matrix of Al. The maximum microhardness of 68.63Hv was achieved in 350 MPa compacting pressure and 9% Mg and SiC. The XRD analysis showed Inter metallic compounds/ phases in the MMC.
