Abstract Scope The oxidation behavior of several Ni-based alloys in high temperature steam was studied in order to evaluate the suitability of these alloys for use in 700 oC A-USC coal-fired power plants. The exposure test in steam at 750 oC was performed with GH 2984, CCA617 and Inconel 740H and the dissolved oxygen (DO) was controlled at about 20 ppb and 5 ppm. Oxidation kinetics were determined by weight gain measurements and oxide scales were characterized by scanning electron microscope (SEM) and X-ray diffractometer (XRD). The results showed that these alloys were oxidized following a parabolic law and the oxidation rate was increased with increasing dissolved oxygen concentration. The oxide formed on the alloys was generally consisted of Cr2O3. Underneath the scale, internal oxidation of Al occurred. Both the external and internal oxides formed at 20 ppb DO were smaller in size in comparison with those formed at 5 ppm DO.
