dc.description.abstractRolling contact fatigue (RCF), a pervasive and insidious problem on all types of railway systems, dominates the cause of maintenance and replacement on heavy-haul rail lines. It also plays a significant role in economic and safety challenge for commuter and metro lines. Intensive research around the world has been taken to improve RCF by introducing different surface modification techniques. Laser cladding has attracted attention because of its advanced and more efficient repairing technique. In this present investigation, influence of laser cladding on wear and RCF of a premium hypereutectoid rail steel, currently used in Australian heavy haul railways, has been studied under a roller-on-disc test rig in laboratory conditions. Rolling test was carried out using a roller made of heat treated harden steel with laser cladded and un-cladded rail steel discs. Micro-hardness of the roller was 820-850 HV5 to minimize plastic deformation and wear of the roller. Considering the real scenario of rail-wheel contacts, tests were run under partial sliding and rolling motion. The maximum contact pressure was similar to that experienced in rail due to rail-wheel contact. Wear resistance of laser cladded specimen was found to be significantly improved compared to non-cladded rail steel. © 1996–2021, American Society of Civil Engineersen_AU
