| Abstract | The high-temperature oxidation resistance of the WC-CrN superhard nanocomposite films was studied at 600 and 700oC in air. The oxidation of the film resulted in the formation of volatile species such as the evolution of carbon probably as CO or CO2, evolution of nitrogen from the film, and the formation of W-oxides. The scale formed was prone to cracking and spallation. |
