Abstract Scope |
Great progress has recently been made toward advancing molten chloride salt systems, particularly for concentrated solar power (CSP) and nuclear applications. However, significant concerns regarding the corrosive nature of molten chloride salts remain. Our team has been working to understand and mitigate corrosion of high-performance alloys in molten chloride salt systems, with a focus on electrochemical solutions. Primarily, we have focused on two aspects of corrosion: 1) Electrochemical mitigation of corrosion caused by the species MgOHCl, which forms in chloride salts when exposed to moisture, and 2) Galvanic corrosion, which alloys are vulnerable to when in electrical contact with both a more noble alloy and the salt, which acts as an electrolyte. |
