Formation and dissolution of porous magnetite layer in contact with lead-bismuth eutectic: Locally equilibrium thermodynamic model
Source abstract
Abstract
Locally equilibrium thermodynamic model is developed to describe the formation and dissolution of the outer magnetite layer of an oxide film on the steel surface in contact with lead-bismuth eutectic. The model allows to predict the outer layer growth law as a function of dissolved oxygen and iron concentrations, temperature and coolant flow rate. Comparison with experiments allows to explain the phenomenon of magnetite dissolution in two experimentally observed cases: when oxygen concentration in LBE is above the solid magnetite stability line and under the high values of the coolant flow rate, without the consideration of mechanical erosion.
