Hard coating application is effective way of cutting tool for hard-to-machine materials such as Inconel, Ti and composite materials focused on high-tech industries which are widely employed in aerospace and automobile industry. In cutting tool, high hardness is one of necessary condition along with high temperature stability. In recent years, high-entropy alloys (HEAs) which consist of five or more principal elements having an equi-atomic percentage were reported by Yeh. It can be possible to significantly extend the field of application in extreme conditions. Base on this understanding, surface coatings using HEAs more recently have been developed with considerable interest due to their useful properties such as high hardness and phase transformation stability of high temperature.
In present study, the nanocomposite coating layers with high hardness on WC substrate are investigated using high entropy alloy target. Reactive magnetron sputtering is considered to be a proper process.
