AB - In this work, AA7075 ˗ SiC (0–8 wt.% @ step of 2%) / marble dust (8–0 wt.% @ step of 2%) / graphite (3 wt.%) hybrid alloy composites have been designed and fabricated via high vacuum casting method as per standard procedure, leading to five samples namely SM-08, SM-26, SM-44, SM-62, SM-80 respectively. Thereafter, possible synergistic impact of the complementary combination of SiC/marble dust reinforcing particulates on physical, mechanical, and sliding wear performance of hybrid alloy composites were investigated followed by surface morphology studies. Taguchi approach has been used for sliding wear parametric optimization and hybrid ENTROPY-VIKOR decision-making technique is used for ranking of material based on performance measures. It is observed that with the reinforcing phase the properties like wear performance, coefficient of friction, density, voids content, compressive strength, and impact strength of composites increases considerably while flexural strength diminishes. Thus, SM-62 alloy composite (having 6 wt.% SiC, and 2 wt.% marble dust) shows better improved overall performance relative to others.
