Wear Studies on Metal Matrix Composites: a Taguchi Approach

1. IntroductionDiscontinuously reinforced aluminium metal matrixcomposites (DRAMMCs) are a class of composite materi-als, which have desirable properties including low density,high specific stiffness, high specific strength, controlledco-efficient of thermal expansion, increased fatigue re-sistance, superior dimensional stability at elevated tem-peratures etc[1]. The most commonly employed metalmatrix composite system consists of aluminium alloy re-inforced with hard ceramic particles usuall…

Wear Studies on Metal Matrix Composites: a Taguchi Approach

An attempt has been made to study the influence of wear parameters like applied load, sliding speed, sliding distance and percentage of reinforcement on the dry sliding wear of the metal matrix composites. A plan of experiments,based on techniques of Taguchi, was pedormed to acquire data in controlled way. An orthogonal array and the analysis of variance were employed to investigate the influence of process parameters on the wear of composites. The objective is to establish a correlation between dry sliding wear of composites and wear parameters. These correlations were obtained by multiple regressions. Finally, confirmation tests were conducted to verify the experimental results foreseen from the mentioned correlations.
