Özet
In this study, the effect of WC coating on the tribological performance of R260 rail steel was investigated by roller-on-plate wear tests and potentiodynamic polarisation corrosion tests carried out in dry and pure water environments. The High-Velocity Oxygen-Fuel (HVOF) method was used for the coating process. The tests were conducted with a weight of 40 N and a sliding speed of 0.03 m/s. An Ag/AgCl reference electrode was also used for corrosion tests in a 3.5 % NaCl solution. To produce cyclic polarisation curves, the experiments were carried out at a scan rate of 1 mV/s within a potential range of ±0.25 V. The effect of WC coating on the wear performance of rail steels was analysed quantitatively with the friction coefficient and volume loss parameters and visually with SEM and 2D-3D topography images. The effect of the coating on the corrosion performance was evaluated numerically with the corrosion …
