Oxidation Resistance of Mild Steels Coated with Ce⁴⁺-Modified TiO₂ Nanofilms

The Ce4+-modified titania nanofilm was deposited onto mild steels by the sol-gel method. The effect of the film on protecting mild steels from oxidation was studied by means of oxidation test, SEM and XRD. It was found that the anti-oxidation effect is increased by Ce4+ modifying and with increasing layer number. When oxidized below 600 degrees C, the Ce4+-modified double-layer titania nanofilm possesses an excellent anti-oxidation performance that is comparable with that of the stainless steel.
