Oxide films and scales formed on Ni-Cr-Mo and Ni-Cr-Co-Mo alloys containing about 19%Cr were studied by electron and X-ray diffraction methods. The following results were obtained. (1) In Ni-Cr-Mo alloys, the rate of formation of spinel phase NiOCr2O3 rose as the molybdenum content was increased, during the early part of oxidation at temperatures of 850° and 1000°C. (2) In the scales of Ni-Cr-Mo alloys, Cr2O3, NiOCr2O3, NiO and NiOMoO3 were formed above 1000°C. NiOMoO3 formed on Ni-Cr-Mo alloys decomposed, releasing MoO3 above 1200°C, and fused at the temperature of oxidation-resistance limit, 1350°C. (3) In Ni-Cr-Co-Mo alloy, formation of spinel phase (Ni, Co)OCr2O3 was expedited, owing to the cobalt content, and the formation of (Ni, Co)OMoO3 was hindered thereby. At the temperature of oxidation-resistance limit of Ni-Cr-Co-Mo alloy, (Ni, Co)OMoO3 was formed and fused.
