The effect of sintering temperature and time on microstructure, hardness and wear behaviors of Al 99.9/GNP composites

In this study, it was aimed to investigate the microstructure, hardness and wear behavior of graphene nanoplate (GNP) reinforced composites with Al 99.9 matrix produced by powder metallurgy. Different temperatures times were applied in sintering process. The values increased as temperature time increased. decreased increase GNP reinforcement ratio. losses depending on time. With ratio, reductions recorded. It has been concluded that element composite structure reduces friction coefficient having some lubricating effect. observed neck bonding formation between grains improved increasing development intergranular bonds, porosity mechanical properties
