Development and Accretion of Tribological Performance on Al-CSA Composites using Orthogonal Array

Abstract This study has been described on optimization of tribological characteristics of Al-coconut shell ash (CSA) reinforced composite prepared with stir casting route. In this study, three operating variable (i.e., load, sliding speed, and % of CSA) and three response (i.e. wear (µm), wear rate (mm3/m), and coefficient of friction) are considered. The experiments are designed using L27 orthogonal array (Full factorial design). The influence of each parameter on the response is established using response tables and response graphs. Based upon experimental data, the model equations for each response were developed with multiple linear regressions. The models give the factor effects of individual parameters. Interaction effects provide additional information to understand the detail behavior of parameters. It reveled that load is the most influencing effect on wear behavioral responses.
