説明
<p>The effect of temperature and gas atmosphere on corrosion behavior of type 316L stainless steel in a molten Li2CO3-Na2CO3 eutectic has been investigated. When the CO2 partial pressure was higher than 0.02 atm and the temperature was lower than 843K, the severe corrosion (localized corrosion) occurred. However, once the sample had been kept for some periods in the melt under N2 (or N2+5%H2O), no severe corrosion occurred, even though the atmosphere shifted to the localized corrosion condition subsequently. From this result, it was revealed that localized corrosion was avoidable by forming LiFeO2 layer on the metal surface in advance. Especially, the addition of H2O into the atmosphere could become effective method to prevent localized corrosion.</p>
