It is becoming increasingly difficult to design new technical materials that are resistant to wear damage and corrosion degradation in severe service circumstances. Unfortunately, even with crucial passive metals, like Al alloys, there is often a compromise between wear and corrosion resistance. Because of the unfavorable galvanic connection between the precipitates and the matrix, precipitates not only harden the material but also accelerate corrosion. This research established that a supersaturated solid solution made of Al and SiC by non-equilibrium techniques had superior corrosion resistance without compromising strength. Energy dispersive X-ray spectroscopy (EDS) and scanning electron microscopy (SEM) were used to examine the microstructure of each sample. Numerous products, such as bumpers and sporting equipment, are made from aluminum-silicon carbide composites for application in engineering, aerospace, marine, automotive, and other fields. The proportion of silicon carbide in a material affects its yield strength and ultimate tensile strength. As silicon carbide content rises as a percentage of the material, total elongation drops. The amount of silicon carbide in an Al-SiC composite determines its hardness. An increase in silicon carbide content reduces wear losses. The microstructure analysis showed that the SiC composite was evenly dispersed throughout the matrix. Each composite has seen an increase in hardness and density thanks to the SiC and Al additions. In addition, the composites’ hardness and density went up when the percentage of these reinforcements used went up.
