Further insights into the mechanisms involved in the corrosion of 316L(N) austenitic steel in oxygenated liquid sodium at 550 °C
Abstract : 316L(N) austenitic steel was corroded at 550 °C in liquid sodium containing ca. 200 $\mu$g g$^{-1}$ 23 dissolved 24 oxygen from 242 h to 7704 h. NaCrO$_2$ is formed for all immersion times, O and Na from liquid metal 25 and Cr from steel. The oxidation front is located at the chromite / steel interface and in the steel grain 26 boundaries. M$_6$C carbides (M = Mo and Fe) are also formed, C from liquid sodium. NaCrO$_2$ is dissolved 27 until the saturation of liquid sodium in Cr is reached. The Cr solubility is higher than that of pure Cr due 28 to the presence of dissolved oxygen.
