Thin Y{sub 2}O{sub 3} films were deposited by the electrochemical deposition-pyrolysis process on Fe-25Cr and Fe-25Cr-10Al alloys. The influence of the films on the oxidation behavior of the alloys was studied at 850{degrees}C and 1000{degrees}C. The results showed that Y{sub 2}O{sub 3} films remarkably decreased the oxidation rate of Cr{sub 2}O{sub 3}-forming alloys and spallation of the scales, but they did not decrease the oxidation rate of the Al{sub 2}O{sub 3}-forming alloys, although they do reduce the spallation of Al{sub 2}O{sub 3} scales. Y{sub 2}O{sub 3} films remarkably change the morphology of the scales on both alloys, depending on the oxidation temperatures. These results show that the reactive-element effects of Y{sub 2}O{sub 3} films on the Cr{sub 2}O{sub 3} formers and Al{sub 2}O{sub 3} formers are different.
