Experimental Analysis Using Taguchi Optimization Technique on Wear Properties of AL-356 Alloy MMC Reinforced with SiC

In the present study, A356 composites with varying silicon carbide particles were produced by stir casting techniques. The developed composites were subjected to wear analysis. The dry sliding wear test of composite was carried out as per ASTM G99 using pin-on-disc wear testing machine using Taguchi L₁₆ approach with varying silicon carbide particles (2, 4, 6, 8, 10 and 12%), load (1, 1.5, 2 and 2.5 N) and speed (200, 300, 400 and 500 rpm). SEM images confirm the uniform dispersion and good bond of SiCp particles with the A356 matrix alloy. According to response table for S/N ratio, the most influence parameter on wear volume was silicon carbide particle content. The worn surface analysis shows delamination and abrasion for composite with high percentage of reinforcement particle content.
