Paper Title:
Comparative Study on Tribological Behaviour between AZ71E and AZ91D Alloys under Ambient and Elevated Temperature
  Abstract

The tribological properties of AZ71E and AZ91D magnesium alloys were comparatively investigated at ambient and elevated temperature. The results indicated that the wear rates of both alloys increased with increasing load, whereas the friction coefficients decreased with increasing load. The wear resistance of AZ71E alloy was significantly superior to that of AZ91D at higher loads and elevated temperature. At ambient temperature, abrasive wear is the predominant wear mechanism for AZ71E, whereas the wear mechanism for AZ91D transfers from abrasive wear to delaminative wear. At elevated temperature, the predominant wear mechanism of both alloys changed from mild wear regime to severe wear regime.
