Abstract

This study's 7075 aluminium uses the potential swirl moulding process, which incorporates silicon carbide, titanium dioxide, and PKSA additives. In this experimental investigation, the weight percentage of the smallest silicon carbide particle was kept constant at 3%. The titanium dioxide content ranged from 2% to 3%, whereas the weight percentage of PKSA was adjusted between 3% and 8%. The produced instances were subjected to a variety of tests, including a mechanical inspection, a microhardness examination, and an overall deterioration evaluation. The maximum tensile stress of this alloy is 8% more than that of the normal alloy. The increased elasticity of these augmented combinations was shown by the elasticity seen in a component. In addition, we saw substantial improvements in the longitudinal stiffness of its material. The microhardness of the solid waste products (PKSA) decreased, indicating their potential suitability for cost-effective reinforcement of a large amount of vehicle components. The degradation tests have been successfully done. There was a notable slowdown in the rate of decline. An extensive examination was performed using the Field Emission Scanning Electron Microscope (FESEM), which unveiled the spatial arrangement of components inside the aluminium composite. 1 Introduction
