Abstract
In present work, the wear behaviour of AZ31B magnesium alloy during dry sliding conditions has been investigated. The experiments were carried out using pin-on-disc type wear apparatus against a steel disc counterface in an applied load range of 10-50 N, sliding velocity range of 0.1-0.9 m/sand at a constant sliding distance of 1000 m. The effect of applied load and sliding velocity on wear rate were analyzed. The wear surfaces were examined using a field emission scanning electron microscopy equipped with an energy dispersive spectrometer to reveal wear features. Microstructural characterization results established different mechanisms at different sliding conditions, namely, abrasion, oxidation, delamination, plastic deformation and melting.
