Abstract

The objective of this study is to preliminary explore the effect of wear on high temperature oxidation performance of U71Mn rail steel. The specimens was tested at 500 N on abrasion testing machine, and then performed at high temperature in the furnace. The surface and cross section was investigated by SEM with EDS. Oxide phase was analysized by XRD. The results showed that deep scratches on wear samples cause the oxide film to fall off seriously, so that the weight gains at high temperature is smaller than that of the non-wear samples. The oxide is rough, unstable and exfoliated easily. The oxidation rate of U71Mn after wear is higher than that without wear. Therefore, the high temperature caused by frequent friction plays an important role in the service life of high-speed trains.
