| Abstract Scope |
Molten halide salts pose a significant risk for material corrosion due to the selective oxidation of certain alloying elements such as chromium. However, it has been shown in past research that the addition of a reducing impurity into the salt mixture can lower the rate of corrosion by interacting with other oxidizing impurities in the salt.
In this work, we have developed a model for predicting the rate of corrosion in molten KCl-MgCl2 salt on Haynes-230 and SS316 alloys with increasing amounts of added magnesium. The resulting model was able to accurately predict a rate of corrosion under these conditions that is verified by experimental measurements. Experiments conducted exposed alloy samples to salt with varying levels of magnesium impurities and analyzed resulting damage after exposure. Results showed a reduction in corrosion rate with increased levels of magnesium addition, as is predicted by the model. |
