Method of depositing a protective layer over a biaxially textured alloy substrate and composition therefrom

摘要

A laminate article consists of a substrate and a biaxially textured protective layer over the substrate. The substrate can be biaxially textured and also have reduced magnetism over the magnetism of Ni. The substrate can be selected from the group consisting of nickel, copper, iron, aluminum, silver and alloys containing any of the foregoing. The protective layer can be selected from the group consisting of gold, silver, platinum, palladium, and nickel and alloys containing any of the foregoing. The protective layer is also non-oxidizable under conditions employed to deposit a desired, subsequent oxide buffer layer. Layers of YBCO, CeO₂, YSZ, LaAlO₃, SrTiO₃, Y₂O₃, RE₂O₃, SrRuO₃, LaNiO₃ and La₂ZrO₃ can be deposited over the protective layer. A method of forming the laminate article is also disclosed.
