In present work, the wear behaviour of ascast 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/s and at a constant sliding distance of 1000 m. The wear mechanism map was drawn. The dominant wear mechanisms were identified in each wear regime. .Microstructural characterization results established different mechanisms at different sliding conditions, namely, abrasion, oxidation, delamination, plastic deformation and melting.
