Abstract: In this study, we present a facile route for the production of thin LaCrO3 layers as a protective layer on chromium-containing steels, usually applied as a dense interconnector material for solid oxide fuel cells or porous supports for metal-supported solid oxide fuel cells. The reactive sol-gel coating method is based on dip coating in aqueous lanthanum acetate/propionate mixtures and subsequent firing. LaCrO3 is formed by a reaction between lanthanum from the coating solution and chromium from the steel. The obtained layers are thin and adhere well to the sample surface. X-ray diffraction reveals the pattern of the LaCrO3 phases. Thermogravimetric measurements show the improved oxidation resistance of LaCrO3-coated steel. Because of the easy-to-apply nature of this method and the wide range of tailoring possibilities, the reactive coating route is a viable alternative to established nitrate- or alcoholate-based wet chemical coating technologies.
