Abstract
Employing the stir casting method, the aluminium 6061 (Al6061) metal matrix composite (MMC) was prepared after supplementing it with 0, 1, 2, and 3 mass fractions of Molybdenum Carbide nanoparticles (nano-MoC). The enhancement in wear resistance and hardness was evaluated before and after adding nano-MoC with the Al6061. To test the wear resistance, a pin-on-disc instrument has been used. The findings confirmed that introducing nano-MoC reinforcement in Al6061 MMC improved wear characteristics of the composite. The rate of wear was found to be decreased with the increment in nano-MoC content and increased with the applied load. Further, the rate of wear had shown the steady increase with the sliding length. However, the rate of wear had attained the saturated value at the sliding length of 1600 m. It can be publicized that Al6061 with 3.0 % nano-MoC had shown a better wear resistance comparing to the plain Al6061. Specifically, the resistance to wear was boosted by 79.68 % at 40 N applied force with 3.0 % nano-MoC.
