Abstract

Abstract The high-temperature corrosion behaviors of Kanthal alloy for an anode current-collector were investigated at 1150 °C in molten silver under an oxidizing atmosphere. The hot corrosion products of Kanthal alloy in the gas section were Al2O3 and Al2O3 and FeAl2O4 obtained after 1 d and 3, 5, and 7 d, respectively. Contrarily, only Al2O3 was identified in the liquid silver section. Isolated patches were observed beneath the outer oxide layer in the gas section, whereas there was no evidence of these in the liquid silver section, and a cohesive Ag-rich layer beneath the oxide layer was shown to retard the corrosion by acting as an effective barrier.
