AbstractThe effectiveness in reducing the corrosion of a ferritic (430) stainless steel at moderate and high temperatures by coating it with a thin, dense layer of La0.8Sr0.2MnO3 was investigated. The thin coating of La0.8Sr0.2MnO3 was found to be effective in reducing the growth of oxide scales on the 430 stainless steel. More importantly, the coated steel samples were found to have significantly lower area specific resistances after oxidation treatments than similarly treated uncoated steel samples. The activation energies of the coated steel samples were significantly lower than those of the oxidized bare steel samples for all treatment conditions studied. SEM and X-ray diffraction analyses provided further confirmation that the thin La0.8Sr0.2MnO3 coating is effective in reducing the growth of oxide scale on the surface of the heat treated steel. This study indicates that, cheap and commercially available 430 ferritic stainless steel, with the protection of a thin, dense coating of La0.8Sr0.2MnO3, may be considered as a potential candidate for usage as the interconnect material in solid oxide fuel cells.
