Corrosion mechanism of SS316L exposed to NaCl/Na2CO3 molten salt in air and argon environments
Abstract
Molten salts are potential energy storage media for solar thermal power, but can be highly corrosive. To investigate molten salt corrosion mechanisms, the oxidation state and structure of SS316L exposed to salt in air and argon environments was investigated using SEM and XANES techniques. It was determined that iron formed mixed Fe<sup>2+</sup> and Fe<sup>3+</sup> states in both environments, with lower oxidation states deeper into the corrosion. Cr<sup>2+</sup> was the primary oxidation state present in the scale for chromium. Reduced salt basicity with lower oxygen concentration favoured the lower oxidation state, whilst Cr<sup>3+</sup> ions were dissolved by the salt.
