Abstract

This study is related to investigation of effect of different processing temperatures on tribological behaviours of high power diode laser treated samples. Laser treatment was applied to R260 grade rail steel specimens with the initial laser power of 1.750 W and a constant scanning speed of 6 mm/s at the different processing temperatures of 1.100 °C, 1.200 °C and 1.300 °C. As a conclusion 0.4, 0.56, 0.53 and 0.57 friction coefficient values were found for untreated and laser treated samples at 1.100 °C, 1.200 °C and 1.300 °C respectively. While it was expected that raise in surface hardness depending on increasing processing temperatures to result in reduction in wear rate and friction coefficient in laser treated samples, contrary an opposite situation in tribological behaviours was found.
