Parametric optimization of squeeze cast AC2A-Ni Coated SiC p composite using taguchi technique

Abstract

This paper mainly focusses on parametric optimization of squeeze cast AC2A Ni coated SiC p composite through Taguchi technique. Composite samples have been cast through squeeze casting for each experimental trial based on L16 orthogonal array. From analysis of variance (ANOVA), it has been found that reinforcement percentage, squeeze pressure, and pressure duration were the casting parameters making significant improvement in the mechanical properties such as hardness and ultimate tensile strength. Reinforcement percentage and squeeze pressure have been identified as the most influencing parameters from the percentage contribution analysis. The optimum parametric setting has been determined through Taguchi technique. It has been confirmed that AC2A-Ni coated SiC p composite obtained for the optimum parametric setting has exhibited better mechanical properties compared to the experimental trials. © 2014 A. R.
