Investigation of corrosion and wear behavior of Al–SiC composite

Abstract

The current study focuses on analysing the mechanical characteristics of a piston ring for a vehicle by substituting the existing metal with non-ferrous material (i.e., aluminium) in the presence of silicon carbide and its various combinations coated with silicon dioxide or tungsten dioxide. In order to create composites made of aluminium metal matrix, the compositions were combined to the necessary extent and stir casting was used. Mechanical testing was used for the micro structural study, and structural characterizations of a metal matrix composite were performed. Tensile strength, impact testing, and flexural tests on metal matrix composites were performed to evaluate their mechanical properties. It was observable that the composites' densities were reduced and their hardness was raised in the presence of silicon dioxide aluminium matrix. The reduction in reinforcing addition was accompanied by a corresponding decline in tensile strength. All of the measured characteristics showed significant differences between the aluminum-Sic metal matrix composites. The Material Morphology was subjected to SEM analysis as well.
