Abstract
Aluminum 7075 has proved its dominance in numerous applications because of its strength and light weight. Recent research in AA7075 has brought high potential in improving wear resistance, corrosion and machinability. This paper is highly concentrated to improve the wear resistance of AA7075 used in automotive applications. This work includes fabrication of AA7075 with predetermined compositions of SiC by using friction stir processing. First, SEM analysis has been carried out to ensure the defect free zone of surface hybrid composites. Secondly, L9 Taguchi array design was used to obtain wear behavior analysis. Based on the experimental results, influencing factor on wear rate and coefficient of friction (COF) was examined. Based on grey relational analysis (GRG) analysis, Load places a major contribution of 54.22% compare to wt. % of Sic and Sliding velocity on wear and COF and improvement in GRG is achieved by 17%.
