摘要：
Oxidation behavior of γ’-strengthened CoNi-base superalloys was investigated with isothermal oxidation tests conducted in air at 800 and 900 ℃, respectively, for 100 h. It is observed that both 30Ni-10Al-4W-4Ti-2Ta（4W2Ta） and 30Ni-10Al-5W-4Ti-1Ta（5W1Ta） alloys exhibit a three-layered oxide scale structure after oxidation. Addition of Ta increases oxidation mass gain of Co Ni-based high-temperature alloys, but the effects on the type and distribution of oxidation products are not significant. However, the oxidation temperature has a great influence on oxide surface morphology and oxidation mechanisms for those two alloys. After oxidation at 800 ℃,the outermost oxide film contains Co3O4, CoO, and NiO, and when the oxidation temperature is 900 ℃, the outermost oxide film contains only CoO.
