AbstractIn this study, head hardening process was applied for R260 quality rails. Microstructures of rails were carried out using Scanning Electron Microscope (SEM). Hardness distribution of head parts were also evaluated for two category samples (heat treatment and non heat treatment). Wear tests were performed under three different loads (10N, 20N and 40N) in both %3.5NaCI solution and dry conditions. Worn surfaces were characterized by Nikon Shuttlepix, Profile projector and SEM. Results clearly show that, head hardened rails exhibited better wear performance especially under load of 10N in dry conditions.
