Abstract

This research aims to evaluate the wear of AA8176 with graphene (10%) reinforcement by novel encapsulation technique and as-cast AA8176 is compared with the composite. A novel encapsulating stir casting method is used for fabricating the samples in both groups. In group 1, AA8176 with the reinforcement of graphene 10% is used and in group 2, as-cast AA8176 is used. The samples were prepared by ASTM E92 standards, and their wear is tested on pin-on-disc equipment. Each group has 20 samples with a G-power of 80%, and α = 0.05 is set for calculating the sample size and the total sample size is 40. The maximum wear is 79% higher in the AA8176 with 10% graphene reinforcement compared with the as-cast AA8176. The t-test statistical analysis shows a significant p = 0.00 (p < 0.05) difference in the mean-variance of wear between group 1 and group 2. Within the limitations of this study, it is observed that AA8176 alloy with graphene 10% reinforcement improves the wear of the material.
