摘要：
Microstructure characterization of corrosion behavior of an alumina forming austenitic (AFA) steel exposed to supercritical carbon dioxide was conducted at 450-650 degrees C and 20 MPa. At low temperature and short exposure times, the oxidation kinetics were parabolic and the oxide scales were mainly composed of protective and continuous Al2O3 and (Cr, Mn)-rich oxide layers. As the temperature and exposure time increased, the AFA steel gradually suffered breakaway oxidation and its oxide scales showed a multilayer structure mainly composed of Fe3O4, (Cr, Fe)(3)O-4, NiFe/FeCr2O4/Cr2O3/Al2O3, FeCr2O4/Al2O3, and NiFe/Cr2O3/Al2O3, in sequence. The corrosion mechanism based on the microstructure evolution is discussed in detail. Published by Elsevier Ltd.
