Abstract
The main goal of this research is to evaluate the surface roughness of AA8176 with reinforcement of nano graphene (10%) by using a novel encapsulation technique and to compare this composite with as-cast AA8176. Using the novel encapsulating stir casting method for fabricating the samples of both groups. Group 1 combines AA8176 with nano graphene reinforcement and group 2 has as-cast AA8176. As per the ASTM standards all the samples were prepared, and the surface roughness testing machine found surface roughness. We must prepare 20 samples for each group with 80% G-power and α = 0.05. The AA8176 reinforced with nano graphene has a better surface roughness when compared with the as-cast 8176 material. The surface roughness in AA8176 with nano graphene reinforcement is 14% lesser than in as-cast AA8176. T-test’s statistical analysis shows a significant p = 0.00 (p < 0.05) difference in the mean variance of surface roughness between group 1 and group 2. Within the limitations of our study, we can conclude that the surface roughness of aluminum alloy is increased by adding the nano graphene (10%) reinforcement.
