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.
