Wear characterization of thick laser cladded high speed steel coatings
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.
