Abstract

Good oxidation and corrosion resistance are required for cutting tools and other industrial components used in high temperature applications. The highest operational temperature of CrN is normally about 500 °C. A denser Cr-N coating prepared by high power pulsed magnetron sputtering - plasma immersion ion implantation & deposition shows oxidation resistance up to 800 °C compare with those prepared by conventional magnetron sputtering. The hardness and corrosion resistance are shown and discussed. The enhanced performance can be attributed to a phase transition from CrN to Cr2N during annealing and there is no obvious oxide formation on the coatings. © 2014 Elsevier Ltd. All rights reserved.
