Summary

Yttria stabilized zirconia (YSZ) thin film coatings have been deposited on different substrates, such as nickel and porous strontium doped lanthanum manganite (LSM) that is a cathode material for solid oxide fuel cells (SOFCs), by electrolytic deposition. the films were processed by cathodic deposition in the solution of the inorganic salts of yttrium and zirconium. A mixture of methanol and water was used as the solvent. the continuous coatings were developed by multiple iterations of ultra thin film depositions, room temperature drying, and intermediate temperature thermal treatment. the cracks in the films after drying were alleviated by reducing the thickness of individual layers and utilizing two different additives, such as hydrogen peroxide (H2O2) and cationic polyelectrolyte poly(dimethyldiallylammomum chloride) (PDDA). the desired thickness and the continuity of the coating were obtained by controlling the metal ion concentration in the solution, deposition current density, deposition time and thermal treatment temperature. the structures of YSZ coatings were characterized using scanning electron microscopy.
