A uniform, dense and defect free Cr2O3 thin film, which is amorphous at ambient temperature, was applied on the surface of intermetallic Fe3Al by electrodeposition reaction sintering, and the effect of this film on the oxidation of Fe3Al at 900℃ in air was studied. The films and the oxide scales were analyzed by TEM, EDAX,SEM and XRD.It is proved that, by surface applied Cr2O3 thin film,a continuous, protective,fine grained α-Al2O3 scale was formed on Fe3Al. As a result, the adherence of the scale and oxidation resistance of Fe3Al were improved.
