Description

The corrosion behavior of MA956 in SCW at 550/600/650℃ was studied. The morphology, structure and elements distribution of oxide film was studied through SEM, EDS and XPS. The weight gain results of 1000 h immersion in SCW shows that MA956 exhibits excellent resistance to corrosion and the surface film is single layer, rich in Al but poor in Fe. A large amount of Al2O3 has been observed on the surface film at temperature of or above 600℃, and the size reaches to 8 μm at 650℃. Meanwhile, the pre-oxidized MA956 has even higher corrosion resistance. The surfaces of the specimens are smooth and intact and no pitting is observed after exposure for 1000 h in SCW. (authors)
