AbstractAl-O-N and Cr-O-N thin films were deposited on superalloy DSM11 by arc ion plating (AIP). The effects of flow rates of oxygen and nitrogen on phase composition and the interdiffusion of various elements at high temperature between DSM11 substrate and NiCoCrAlY coating were studied in the systems of DSM11/NiCoCrAlY, DSM11/Al-O-N/NiCoCrAlY and DSM11/Cr-O-N/NiCoCrAlY. The results indicate that the Al(Cr)-O-N films are polycrystalline with phase constitution of alpha-Al2O3 + hexagonal AIN or Cr2O3+CrN, respectively. The relative intensity of AIN to Al2O3 or CrN to Cr2O3 is changed with the change of flow rates of oxygen and nitrogen. After oxidation at 1050 degreesC for 100 h, Al-O-N hindered the interdiffusion of elements between DSM11 and NiCoCrAlY more effectively than Cr-O-N film. The diffusion barrier layers hardly influenced the oxidation kinetics of the NiCoCrAlY coating.
