Abstract

To evaluate the application prospect of alumina-forming austenitic stainless steels in supercritical carbon dioxide nuclear reactors, the general corrosion behavior of two alumina-forming austenitic stainless steels (904L-2.5Al and 904L-3.5Al stainless steels) and its base steel (904L stainless steel) in supercritical carbon dioxide (sCO₂) at 600℃ and 20 MPa was investigated through experiments. The corrosion kinetics of materials are evaluated by weight gain method, and the morphology, structure and chemical composition of materials before and after corrosion are analyzed by scanning electron microscope, transmission electron microscope and energy dispersive spectrometer. The results show that the weight gain of all materials approximates the parabolic growth law. The weight gain is lowered by increasing the content of Al, and 904L-3.5Al stainless steel has the lowest weight gain. After exposure, Fe-rich oxide is formed on the surface of 904L stainless steel, and carburization occurs. Continuous Cr/Al-rich oxide scales are formed on the surface of 904L-2.5Al and 904L-3.5Al stainless steels, while no carburization is occurred. Higher Al content facilitates the formation of protective Cr/Al-rich oxides on the material surface, which improves the oxidation and carburization resistance of materials after exposure to sCO₂.
