Abstract: High temperature corrosion properties of M38 alloy with and without 0. 04 wt-%Y and 0.05wt-%Ce additions were studied in equilibrated SO2+O2 gas mixtures at 850℃ and 900℃.It was found that adding Y or Ce decreased the corrosion rate of M38 and changed considerably the surface morphologies and composition of corrosion products on M38. The effectiveness of Y and Ce were also discussed.
