Effect of Reinforcement Surface Area on Tribological Behaviour of Aluminium Alloy Nanocomposites

Abstract Current research work is focused on evaluating the influence of Graphene/SWCNT/MWCNT addition on the tribological properties of developed composites. AA 6061 with varying alloying elements, well known for structural application are used as matrix. XRD analysis, relative density and hardness measurement are performed on the nanocomposites. Dry friction wear test is conducted to evaluate the wear performance of developed nanocomposites under various normal load (N) and sliding speeds (m/s) at ambient temperature. Corresponding wear loss (gm) and friction coefficient were measured to evaluate the efficiency of the composite in terms of tribological performances. Wear tracks and wear debris were analyzed through scanning electron microscopy (SEM) and Raman spectroscopy.
