Corrosion behavior of Fe-Cr-Ni-Zr alloys in aggressive environments at high temperatures

OSTI ID:5863873
The following influences of Zr on the scaling behavior of Fe-Cr-Ni alloys have been observed: (a) additions of 1 to 6% Zr promote protective oxide scale formation on the 12% Cr alloy in air; (b) a concentration of >3% Zr is required to promote protective oxide scale formation on 12% Cr alloys in a S-free, low-p//sub O/sub 2// environment; and (c) in mixed-gas environments, Zr reduces surface scale thickness, generally reduces sulfur penetration into the alloy, and shifts the threshold boundary to lower p/sub O/sub 2// for the 25% Cr alloy. 3 figures.
