“…According to the structural distribution of the oxide layer of the three heat‐resistant steels, the oxidation mechanism can be divided into two cases. [ 33 ] Case 1: When the reaction temperature is lower than 509.3°C, the Gibbs free energy of Fe reacting with steam to form Fe 2 O 3 is less than zero, and Fe 2 O 3 can be formed. At this time, the oxide layer structure from the gas side to the substrate side is the Fe 2 O 3 layer, Fe 3 O 4 layer, and FeCr 2 O 4 layer.…”

The corrosion behavior of KT5916, 2Cr11Mo, and Co3W3 in high-temperature and high-pressure steam at 600°C, and 20 MPa were investigated. The kinetic weight gain curves of KT5916 and Co3W3 nearly followed a parabolic law. Oxide scale exfoliation was found in all steels. The oxide layer structural distribution of the three heat-resistant steels was Fe 3 O 4 layer and FeCr 2 O 4 layer from the gas side to the substrate side, and the critical criterion for the formation of Fe 2 O 3 oxide was 509.3°C. Under the influence of growth stress, the oxide film of the three heat-resistant steels experienced a stable oxide layer, coarsening of oxide, pulverization of oxide, and exfoliation of oxide in high-temperature and high-pressure steam environments.

The supercritical carbon dioxide Brayton cycle is a promising power conversion option for green energies, such as solar power and nuclear reactors. The material challenge is a tremendous obstacle for the reliable operation of such a cycle system. A large body of research indicates that high-temperature corrosion of heat-resisting alloys by CO2 results in severe oxidation and, in many cases, concurrent internal carburization. This paper mainly reviews the oxidation behavior, carburization behavior and stress corrosion behavior of heat-resisting alloys in high temperature CO2. Specifically, the main factors affecting the oxidation behavior of heat-resistant alloys, such as environmental parameters, surface condition and gaseous impurity, are discussed. Then, carburization is explored, especially the driving force of carburization and the consequences of carburization. Subsequently, the effects of the environmental parameters, alloy type and different oxide layers on the carburizing behavior are comprehensively reviewed. Finally, the effects of corrosion on the mechanical behavior and stress corrosion cracking behavior of heat-resisting alloys are also summarized. The corrosion performances of heat-resisting alloys in high temperature CO2 are systematically analyzed, and new scopes are proposed for future material research. The information provided in this work is valuable for the development of structural material for the supercritical carbon dioxide Brayton cycle.
