Characterization of Ceria Stabilized Zirconia Coatings on Metal Substrates

Abstract

In this study ceria stabilized zirconia was used to obtain an uniform and adherent film on iron and 304 S.S.. Coatings were prepared by dipping in solutions of organometallic precursors of zirconium and cerium. Structure and morphology of samples were investigated using SEM and XRD techniques before and after thermal treatments. The oxidation behaviour in air of coated samples was followed through thermogravimetrical analysis in a range of temperature from 773 K to 1123 K. The preliminary results show, for the samples coated and pretreated in high vacuum at 923 K, a good decrease in oxidation rate.
