摘要：

Thin Y2O3 films were deposited by the electrochemical deposition-pyrolysis process on Fe-25Cr and Fe-w25Cr-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 shouted that Y2O3 films remarkably decreased the oxidation rate of Cr2O3-forming alloys and spallation of the scales, but they did not decrease the oxidation rate of the Al2O3-forming alloys, although they do reduce the spallation of Al2O3 scales. Y2O3 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 Y2O3 films on the Cr2O3 formers and Al2O3 formers are different.
