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. BaZrO3 and La2Zr207 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 La2Zr207 as top coating film. © 2018 IEEE.
