AbstractSpray 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 1000°C to study the diffusion and oxidation behaviours. Characterization results indicated that the coatings are dense, have good adhesion to the substrate, and are stable and effective to prevent Cr outward diffusion at the high temperature.
