Abstract Scope |
Molten salts are increasingly considered as potential coolants and breeder blankets for nuclear fission and fusion power systems. However, the interaction between molten salts and structural materials often leads to selective dissolution corrosion. The resulting corrosion morphologies, following an equivalent removal of susceptible atoms, can vary significantly due to the interplay of different kinetic processes, which are highly sensitive to the initial conditions of the sample, such as annealing or polishing treatments performed prior to corrosion testing. We have conducted corrosion testing on samples prepared with different pre-corrosion treatments, indicating that certain preparation methods can substantially alter the corrosion outcomes, while others have minimal impact. This underscores the importance of appropriate sample preparation to achieve meaningful corrosion testing results and highlights the necessity of considering material processing techniques prior to their application in molten salt environments.
