Abstract

In this study, the TiB2 & ZrO2 incorporated A356 based hybrid composites were fabricated via stir casting method and also the wear parameters such as wear rate (WR) and coefficient of friction (COF) were optimized using Taguchi-Grey Relational Approach (GRA). It was found that 10 N of load, 2 m/s of Sliding velocity, 1500 m of sliding distance and reinforcement of 0.5%TiB2+ 2.5%ZrO2 nano particle as the optimal conditions to acquire the minimum WR and COF. The uniform dispersion of nano particles in the matrix alloy was found out with microscopic examination. Analysis of variance results revealed load and incorporation of nano particles as the factors that have dominant influence on WR and COF respectively in that order. Significant improvement in wear resistance rate was obtained with the addition of TiB2 and the COF prominently got reduced with the reinforcement of increased wt% of ZrO2
