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. © 2019 The Authors. Published by Elsevier Ltd.

Graphene being one of the allotropes of carbon, has attracted and evoked keen interest in recent times as an ideal reinforcement for the composites due its outstanding strength. In the current research work, the fatigue and wear behavior of Al6061âGraphene (varying weight fraction 0.2, 0.4, 0.6Â&nbsp;wt%) particulate composite are investigated in comparison with monolithic alloy. Initially dispersion of Graphene is carried out by ultra-sonication followed by ball milling on adding Al6061 alloy powder, consolidated by powder metallurgy process and subjected to sintering under inert gas atmosphere. The investigation on the effect of Graphene flakes on micro hardness, mass loss, coefficient of friction and surface roughness values are done under different loading conditions for the prepared samples and wear tracks are analyzed under a microscope. The possible reasons for crack initiation and subsequent fatigue failure under cyclic loading with stress ratio RÂ&nbsp;=Â&nbsp;â1(sinusoidal waveform), cyclic frequency 5Â&nbsp;Hz and stress amplitude 40â140Â&nbsp;MPa at room temperature conditions and the type of wear due to increase in Graphene weight fractions were studied through tests results and SEM characterizations.
