The Effect of Rail Material on Wear Behavior of Wheel and Rail

This study investigates the effect of rail material on their wear behavior of rail-wheel system by using MMS-2A twin-disc abrasion tester. When one type of wheel matches with different types of steel rail, the worn lose of the steel rail decreases with the increasing hardness, and the abrade wear of wheel increases. The trend showed by the SEM micrograph of the wear scar was consistent with the results of the worn lose.
