摘要：
Four kinds of pearlite and one kind of carbide free bainite rail material are selected to conduct friction and wear tests with CL60 wheels materials separately. Through the simulation of contact stress state of heavy haul railway in laboratory, the wear resistance differences of wheel-rail with different materials during friction are studied, and the surface damage morphology, contact fatigue resistance and wear mechanism of wheel-rail are analyzed. The results show that the wear resistance of U78CrV heat-treated rail is the best among the five kinds of rails with different strength, while that of bainite hot-rolled rail is relatively poor, but the wear loss of the wheel grinding with the bainite rail is relatively minimum under the same conditions. With the increase of cycle times, the surface damages of pearlite and bainite rail samples develop from pitting corrosion to continuous peeling, and the main wear mechanism belongs to surface contact fatigue wear. Bainite rails embrace excellent resistance to fatigue crack initiation, and the crack depth and length are smaller than pearlite rails in the early wear stage, showing better contact fatigue resistance. The work hardening degree and the surface hardness of bainite rails after wear tests are lower than those of pearlite rails, which is one of the reasons why their wear resistance is inferior to that of pearlite rails. © 2022, Editorial Department of China Railway Science.
