Effect of Steel slag on Wear Characterization of Aluminium Composite Using Taguchi Technique

Abstract

A wear behavior of steel slag reinforced aluminium A356 composite was fabricated by stir casting technique. Here an attempt has been made by reinforcing steel slag particle of size (1-5micron) in the aluminium matrix alloy fabricated through stir casting process. Dry sliding wear behavior of the composite was studied by pin on disc method. The experiment was conducted through Taguchi technique. A L16 orthogonal array was developed using ANOVA and the regression analysis was determined to find the optimum parameter. The parameters such as applied load, sliding speed, percentage reinforcement, and the distance travelled are considered for wear test. By considering the' smaller the best' the dry sliding wear was analyzed. Based on analysis of variance (ANOVA) the single-to-noise ratio are used to investigate the wear rate parameters. By studying the SEM analysis the worn out parts are studied.
