| Abstract Scope |
The corrosion performance of high-temperature alloys is crucial in the design of systems like molten salt reactors (MSR) and pyroprocessing facilities. While extensive research has focused on the corrosion behavior of these alloys in molten salts under inert atmospheres, the inevitable presence of oxygen and moisture in real-world facilities presents a critical, yet less explored, challenge. This study investigates the materials performance of several high-temperature alloys under atmospheric ingression conditions, focusing on the impact of oxygen and moisture. The salt conditions such as salt redox potential and corrosion product concentration were in situ monitored electrochemically to gain real-time insights into the corrosion processes. Furthermore, the efficacy of various protective coatings in enhancing the corrosion resistance of these alloys under such conditions is evaluated. This research provides insights into material selection and coating strategies for robust and reliable high-temperature molten salt systems operating in non-ideal environments. |
