Using nanomechanics to optimize coatings for cutting tools

Trends in high-speed machining involve operating at higher cutting speeds and under dry or minimum quantity lubrication (MQL) conditions [1], putting greater demands on the mechanical properties of the tool materials during the cutting process. To improve the quality and wear resistance of the coatings applied to cutting tools and to extend tool life, it is necessary to optimize the coating microstructure, the oxidation resistance, the thermal …
