Aluminum powders were mixed to magnesium (AZ31) chips with various contents and then mechanically alloyed (MA) for 54ks. The obtained MA powder bonded to magnesium rod by compressive deformation for improvements of wear and corrosion properties. Ring of quench-hardened steel (SKD-11) was slid on bonded MA alloy surface under various conditions of sliding speed and normal force using ring-on-disk type wear tester. Friction and wear properties of MA alloy surface were investigated and they were compared with magnesium alloy (AZ31). Wear loss (worn volume) in the MA alloy surface decreases with increasing of Al content. The wear loss in Mg-61.5mol%Al MA alloy surface reaches to one third of the case of AZ31 alloy.
