    Abstract

    The wear behavior of three laser cladded high speed steel (HSS) alloys and one conventional spun cast HSS alloy was investigated by using a pin on disc tribometer at room temperature as well as at 500°C. Due to higher hardness and refined microstructure, laser cladded HSS alloys showed superior wear resistance and steady coefficient of friction at room temperature. But at 500°C, the casted HSS alloy showed the best wear resistance due to the rapid development of a stable oxide tribofilm. Among the laser cladded HSS alloys, the alloy with greater carbide volume fraction showed superior wear resistance at 500°C.
