Abstract Scope |
Understanding the corrosion of alloys in molten salts is important to the development of sustainable energy systems. Metal ions from dissolved fission products and structural materials alter the reaction kinetics between the metals and the salts. Prior microscopic studies on reacted samples highlighted the importance to understand the morphological and chemical changes of the materials in molten salt corrosion. In this work, the corrosion of the eutectic KCl-MgCl2 with 1 wt.% of NiCl2, EuCl3 and CeCl3 on Ni-20Cr at 700°C was studied. In situ synchrotron X-ray nano-tomography was used to visualize and quantify the evolution of the morphological changes of Ni-20Cr alloys. The corroded Ni-20Cr and salt were further characterized by transmission electron microscopy coupled with spectroscopy. The influence of the additives on the kinetics of the corrosion is discussed to compare the differences in the development of a porous structure in these systems. |
