Abstract:Spray pyrolysis deposition is a cost-effective process to deposit films of a wide variety of materials, especially solid oxides. In this study, spray pyrolysis deposition was used to deposit 2-3 μm thick Mn1.5Co1.5O4 spinel and Ta2O5-doped CeO2 on a ferritic stainless steel as protective coatings on SOFC interconnect. The coated samples were exposed to air at 1000oC to study the diffusion and oxidation behaviours. Characterization results indicated that the coatings are dense, have good adhesion to the substra… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
