Wear Analysis by Taguchi Technique of Al6061 Based Hybrid Composite Reinforced with Sic and Al2O3

In this paper, wear characteristics of hybrid composite of Al6061 was studied.Hybrid composite was reinforced with silicon carbide (SiC) with varying (3%, 6%, 9%) weight % and keeping the alumina (Al2O3) with constant (10) weight percentage.Stir casting method was used to fabricate the composite.T6 heat treatment was applied on the sample before doing the wear test.Pin on disc apparatus was used to perform the wear test.SEM was performed to do the microstructural analysis.It was found that hardness and density of samples increased as the percentage of SiC increases.L9 orthogonal array was applied to check the interaction between different wear parameters using the Taguchi technique.
