Zirconium Perowskite Coatings Obtained by Combinatorial EB-PVD Process

New coating materials for high temperature conditions have been developed by a combinatorial electron beam physical vapor deposition process (EB-PVD) on different metallic substrates. BaZrO

nanostructured powders obtained by a hydrothermal process and hydrostatically pressed in pellets were used as starting material. The coatings were characterized by XRD, SEM and EDX. Our preliminary results show that thin films with controlled morphology could be obtained when both materials are deposited layer by layer with La
