Abstract

The corrosion of AISI 316 steel has been investigated in sodium polysulphide melts in the region between 300 and 410°C which is of interest with respect to the Na/S battery. Although AISI 316 is not suitable as a corrosion-resistant casing material, it can serve as a model material for the elucidation of basic mechanisms. Both anodic and cathodic potentials were applied in order to represent the conditions in a cell. The corrosion products formed multilayer scales, the inner one consisting primarily of chromium sulphide which acted as a corrosion barrier. The corrosion reaction had an activation energy of 105 kJ mol−1. In the higher temperature region the scale dissolved partially in the melt due to a change in the scale morphology. Possible mechanisms for anodic and cathodic corrosion reactions are discussed.
