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.},
