Paper Title
Wear Rate Modelling and Analysis of Friction Stir Welding of Al6061 /Sic Composite

Abstract
Al 6061 metal matrix composites with SiC are increasingly becoming popular in automotive, aerospace and electronics industries, in view of their excellent mechanical properties and wear resistance. Metal matrix composites (MMCs) have emerged as an important class of materials, which are increasingly being utilized in recent years. Their wide application as structural materials needs proper development of suited joining processes. The present study investigates the effect of joining parameters like tool rotation speed, welding speed, axial force and different % wt. of SiCp on the wear rate (W) and wear resistance (R). Central composite design (CCD) was employed in developing an efficient mathematical model for wear rate. Analysis of variance (ANOVA) was used to test the adequacy of the developed mathematical model. The contour plots were generated to study the effect of process parameters as well as their interactions. Keywords— Metal Matrix Composites, Friction Stir Welding, Welding Parameters and Contour Plot.
