Electrochemistry of molten salt corrosion

Abstract Thermodynamics and electrochemistry are of great importance in understanding and controlling corrosion. Molten salt corrosion has been mainly studied by the surface observation and gravimetric method. Electrochemical techniques have also been applied to this system in order to obtain information on the selection of materials and estimation of corrosion mechanisms. In this paper, the electrochemical theory and concepts of molten salt corrosion are briefly described as well as thermodynamics, and then an overview of the electrochemical evaluation methods of molten salt corrosion is given.
