Scanning electron microscopy and cyclic voltammetry were used to investigate the high-temperature oxidation behavior of two solid oxide fuel cell interconnect steels. One alloy had a low content of manganese; the other alloy had a high content of manganese. Four reduction and four oxidation peaks were observed in the voltammograms of the low manganese alloy at a temperature of 800 A degrees C. The voltammograms of the alloy with a high content of manganese were different. At 600 A degrees C, three reduction peaks and two oxidation peaks were observed. At 800 A degrees C, additional peaks were observed in the voltammogram for this alloy.
