Friction and Wear Property of Pure Magnesium

The friction and wear properties of pure magnesium are investigated using M-2000 machine under dry sliding conditions with different loads, different sliding distance. The morphology of worn surface of pure magnesium was analyzed by SEM in order to understand the predominant wear mechanism of pure magnesium. The results show that the friction coefficients of pure magnesium would decrease with the load increase, and have a little effect with the sliding distance. The wear loss of pure magnesium would enhance with the load and sliding distance increase. With the load increase, the wear mechanism of pure magnesium included oxidation wear, abrasive wear, delamination wear and fatigue wear.
