Abstract

The oxidation behavior of three Ni-Fe-Cr alloys with different contents of Cr was studied in supercritical water at 700 ℃ under 25 MPa. Oxidation kinetics was acquired by weighting samples at intervals. After oxidation, the surface and cross-sectional morphologies, and phase compositions of the oxide scales were investigated using SEM/EDS and XRD. The results showed that the high Cr-content enhances the oxidation resistance of Ni-Fe-Cr alloys in supercritical water, i.e. lowering the mass gains and postponing the onset of breakaway oxidation. In supercritical water, the critical concentration of Cr, needed for the formation as well as sustained and steady growth of the protective chromia scale on Ni-Cr-Fe alloys, is higher than that in air. And in supercritical water, the protective Cr-rich oxide scale forms after a short time exposure. However, this protective Cr-rich oxide scale transforms to non-protective scale more easily in the further oxidation process. As exposure time increases, a duplex oxide scale forms on the alloy with low Cr concentration, and Ni-rich oxide exists in between the two oxide layers.

Key words: Ni-based alloy Cr content supercritical water high temperature oxidation
