An Analysis of the Solute Interactions in Multicomponent Metallic Solution to Study the Liquid Metal Corrosion Mechanisms in Sodium

Abstract:

It is demonstrated that using the mathematical formalism of the interaction parameters for multicomponent metallic solution, it is possible to predict mass transfer in a system consisting of two dissimilar metals separated by low-melting one containing non-metallic impurities. The calculation of the interaction parameters in three-and four-component systems was carried out using the equations of the coordination-cluster model. Comparison between theory and data reported in the literature for corrosion in sodium loop led to the conclusion about the most probable mechanism of the influence of the oxygen impurity content on the corrosion rate of iron under non-isothermal conditions.
