Al 5251-based hybrid nanocomposite by FSP reinforced with graphene nanoplates and boron nitride nanoparticles: Microstructure, wear, and mechanical characterization

Abstract The strength and wear resistance of aluminium alloys must be improved to enhance their usage in lightweight constructions. Thus, this study, graphene nanoplates (GNPs) boron nitride (BN) nanoparticles were reinforced into the Al 5251 alloy by friction stir processing (FSP). aluminum sheets patterned with holes filled mono GNPs, BN a hybrid GNPs. microstructure, wear, mechanical properties as-received, after FSP, manufactured surface nanocomposites analysed. Wear tests performed using two methods: weight loss volume methods. FSP led four times grain refinement. Due Zener pinning effect, reinforcement refinement effect seven decrease mean size. rate reinforcing decreased 160 1,340%, respectively. Note that GNP insignificantly hardness compared nanoparticles. was increased 50, 120, 80% BN, nanocomposite GNPs exhibited superior other nanocomposites.
