Wear and mechanical characterization of Mg-Gr self-lubricating composite fabricated by mechanical alloying

In this research, the wear and mechanical responses of pure magnesium-graphite (Mg–Gr) composite have been investigated aiming to get the optimum composition of reinforcement. The composite materials were fabricated by mechanical alloying. The percentage of graphite reinforcement was chosen as 3, 5,...
