Abstract
Sliding wear behavior of newly developed of magnesium base hard alloys containing magnesium borides carbon steel (SUJ2) wear studied by ring-on-block type Ogoshi wear resislance teste at sliding velocities of 3.55m/s, load of 20.6N and sliding distance of 66.6m to 600m. The new hard alloys exhibits better wear resistance and gives less than conventional magnesium alloys. The excellent wear performance of the new hard alloys are attributed to the improvement of hardness and the formation of oxides such as MgO and B2O3, which may act as lubricants during slides.
