摘要

Magnesium also possesses several advantages, including improved manufacturability, increased machinability, and a lower latent heat of fusion than other metals. As a result, the AZ31 magnesium alloy is selected to serve as the foundation matrix. Tungsten carbide Nanoparticles made of tungsten carbide (WC) are used because of their high hardness (1400 HV), high melting point (2870 °C), high modulus of elasticity (630 GPa), good oxidation resistance even at high temperatures (up to 600 °C), good thermal conductivity (85 W/m-K), and good shock absorbing capability. These characteristics make them an ideal choice for use as reinforcement. The ultrasonic vibration-assisted stir-casting can effectively disperse nanoparticles throughout the magnesium melt. The tribological behavior of produced nanocomposites, including wear and friction, is explored under various working situations, considering load, speed, and sliding distance variables.
