  • METHOD OF DEPOSITING BUFFER LAYERS ON BIAXIALLY TEXTURED METAL SUBSTRATES
    Publication number: 20020134300
    Abstract: A laminate article comprises a substrate and a biaxially textured (RE1xRE2(1−x))2O3 buffer layer over the substrate, wherein 0<x<1 and RE1 and RE2 are each selected from the group consisting of Nd, Sm, Eu, Ho, Er, Lu, Gd, Tb, Dy, Tm, and Yb. The (RE1xRE2(1−x))2O3 buffer layer can be deposited using sol-gel or metal-organic decomposition. The laminate article can include a layer of YBCO over the (RE1xRE2(1−x))2O3 buffer layer. A layer of CeO2 between the YBCO layer and the (RE1xRE2(1−x))2O3 buffer can also be include. Further included can be a layer of YSZ between the CeO2 layer and the (RE1xRE2(1−x))2O3 buffer layer. The substrate can be a biaxially textured metal, such as nickel. A method of forming the laminate article is also disclosed.

  • Laminate article
    Patent number: 6399154
    Abstract: A laminate article comprises a substrate and a biaxially textured (RExA(1−x))2O2−(x/2) buffer layer over the substrate, wherein 0<x≦0.70 and RE is selected from the group consisting of La, Nd, Sm, Eu, Gd, Th, Dy, Ho, Er, Tm, Yb, and Lu. A is selected from the group consisting of Zr+4, Ce+4, Sn+4, and Hf+4. The (RExA(1−x))2O2−(x/2) buffer layer can be deposited using sol-gel or metal-organic decomposition. The laminate article can include a layer of YBCO over the (RExA(1−x))2O2−(x/2) buffer layer. A layer of CeO2 between the YBCO layer and the (RExA(1−x))2O2−(x/2) buffer layer can also be include. Further included can be a layer of YSZ between the CeO2 layer and the (RExA(1−x))2O2−(x/2) buffer layer. The substrate can be a biaxially textured metal, such as nickel. A method of forming the laminate article is also disclosed.
