The effect of single reinforcement nanoparticles on the AA3105 aluminum alloy fabricated by FSP: mechanical properties and wear behavior of composite matrix

This study investigates the impact of incorporating single reinforcement nanoparticles, namely Boron Nitride (BN), Graphene (G), and Carbon Nanotubes (CNT), on the mechanical properties (hardness) and wear behavior of AA3105 aluminum alloy fabricated using the Friction Stir Processing (FSP) method. The research focuses on enhancing the sliding wear resistance of AA3105 by reinforcing it with these nanoparticles. The novelty lies in reinforcing the aluminum substrate with solid lubricant ceramic particles like BN and enhancing the dispersibility of these nanoparticles in the aluminum melt through surface modification with salts. The study explores the potential for developing wear-resistant, self-lubricating aluminum 3105 bushings suitable for extreme environments such as bushings in aerospace and automotive industries, leveraging the alloy's ductility, formability, and corrosion resistance. The AA3105-CNT composite exhibited the most significant improvement, with microhardness increasing by 39.1% and wear resistance enhancing by 17% compared to the base alloy. The incorporation of BN nanoparticles resulted in a 16.2% increase in microhardness and a 36% enhancement in wear resistance.
