Abstract
Main focus of this research work is to analyze the impact of mechanical behaviour (hardness) and tribological behaviour (wear properties) of Graphene reinforced Magnesium alloy (AZ91D) consisting of metal matrix compound. During this analysis, 1% reinforcement found in Graphene molecules by weight to the Mg alloy (AZ91D) to generate a compound by applying the technique of bottom poured stir casting. Wear analysis technique (wear and frictional coefficient) has been incorporated on the DUCOM pin and on the setup of disc tribometer, with the utilization of metal matrix composite (MMC). For experimental designs, Taguchi’s optimization technique has been incorporated. To study the wear resistance phenomenon of the MMC, “Smaller the better” criteria have been taken into consideration as an objective model. The operating parameters like applied load (30 N, 40 N, 50 N), disc rotating time (4, 6, 8 min) and disc rotational speed (500, 650, 800 RPM) are optimized through analysis of variance (ANOVA) along with signal to noise ratio analysis. From the statistical study of ANOVA, finally, it is concluded from the observation that tribological behaviour is significantly affected by rotational time and the load applied on the disc.
