Paper Title:
High Temperature Oxidation of WC-ZrN Superhard Nanocomposite Film
  Abstract

The high-temperature oxidation behavior of WC-ZrN superhard nanocomposite film was studied in air between 500 and 700oC. The WC-ZrN film displayed poor high-temperature oxidation resistance, because of the formation of the nonprotective W-oxide scale and the less-protective, nonstoichiometric ZrO2-x oxide scale. The scale was prone to cracking and spallation. During oxidation, C and N escaped from the film into the air, while oxygen from the air diffused into the film.
