Modeling the competitive relationship between wear and rolling contact fatigue of railway wheel steel
Wear and spalling caused by rolling contact fatigue (RCF) are common failure modes on the tread of railway wheels. The competitive relationship between wear and RCF in heavy-haul railway freight wheel steel was investigated. Wear and RCF tests under dry friction and oil lubrication conditions were conducted on the wheel steel with three different hardness of A# (329 HB), B# (341 HB), and C# (355 HB). The outer surface and cross-section of the specimens were observed using a scanning electron microscope and an optical microscope. The results indicate that the failure type of wear dominates the competitive relationship between wear and RCF in the wear tests, and the failure type of RCF dominates the competitive relationship between wear and RCF in the RCF tests. A significant plastic deformation layer was observed on the cross-section of specimens in the wear tests, while noticeable spalling cracks were found on the cross-section of specimens in the RCF tests. The higher the hardness, the deeper the crack propagation. Based on the Archard wear model and a RCF model, a model and a competition coefficient TC were proposed to describe the competition between wear and RCF. when , wear dominates corresponding to the wear tests. when , RCF dominates corresponding to the RCF tests. Wear and RCF are in a relative balanced state when .
期刊介绍：
Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
