Coated conductors on tubular metallic wires by combined chemical approaches

Résumé

Fabrication of YBCO wires has been explored by using tubes formed from textured tapes. The texture of tubes made from Ni-5 at % W is characterized as a bi-axial texture developing along both the axis and the circumference of the cylinder. The deposition of a buffer layer by metal-organic deposition on such a tube is described with the practical example of La2Zr2O7. A superconducting YBCO layer is deposited on top; its texture and the electrical performance are evaluated. In the present state of the art, the YBCO is superconducting at 88 K; it is textured, but can carry only week supercurrents due to insufficient percolation paths. Improvements of the process are underway to enhance the transport current properties
