Corrosion Behaviors of Heat-Resisting Alloys in High Temperature Carbon Dioxide.

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 CO results in severe oxidation and, in many cases, concurrent internal carburization.
