英文摘要	The high-temperature oxidizing behaviors of a new Ni-Cr-Mo-Cu nickel-base corrosion-resistant alloy at 600°C, 800°C and 1000°C were studied by using static isothermal oxidation method, and the phase structure and morphology of oxidation layers of the alloy were analysed by XRD and SEM. The results show that the oxidizing dynamics curves of Ni-Cr-Mo-Cu alloy obey approximately the cubic parabolic law, its oxidation process after 10 hours is mainly controlled by ion diffusion. The compact oxidation film forms on surface of the alloy, the main oxides of the film are Cr2O3, NiO and NiCr2O4. The rate constant of oxidation reaction of Ni-Cr-Mo-Cu alloy is 1.296 × 10-8exp (-Ea/RT) and its activity energy is 200.25 kJ/mol which is between those of Cr2O3and NiO oxidation layers.
