Investigation on Wear Analysis of Aluminium (Al) 7075 Alloy Reinforced with Titanium Carbide (TiC) and Graphene (Gr) Nanoparticles

Abstract:

In this study wear behavior of metal matrix nanocomposites covers a distinctive mixture of Al 7075 reinforced through Titanium Carbide (TiC) and Graphene in nanoform. Present work consists of Al7075 base metal is reinforced with nanopowder TiC (2.5 % wt.) and Graphene (0.25% wt.). The samples casted by ultrasonic stir casting technique and machining in accordance with ASTM standards, then tested for wear behavioral characteristics using pin on disc. This method was functional to determine the effect of three factors like sliding velocity, applied load and sliding distance for the above work by using the Taguchi method. By considering three factors, three levels, and the composition of nanoTiC (2.5%) by keeping a constant Graphene (0.25% wt.), the applied load variations in steps are 10 N, 20 N, and 30 N, the sliding velocity is 1.5m/sec, 2.5m/sec, and 3.5 m/sec, and the sliding distances 500m, 1000m, and 1500 m to study the wear behavior.
