In 700C steam environment, the FeCrAl-coated Zry2 samples have significantly reduced the oxidation rate, compared to the uncoated Zry2. Alumina was promoted for FeCrAl with high Al composition, and a parabolic alumina growth rate under 700_C steam exposure was quantified by AES depth profile. Zirconia formation was inhibited by the FeCrAl coating. A thicker film proved to be more protective, and delayed zirconia formation for a longer time. In 1100C steam environment, a complete film loss was observed due to the low eutectic temperature (950C) of the Fe-Zr binary system.","abstract_html":"Iron-Chromium-Aluminum (FeCrAl) thin films have been deposited on Zircaloy-2 (Zry2) and yttria-stabilized zirconia (YSZ) by magnetron sputtering, and they have been tested with respect to the oxidation weight gain in high temperature steam.
