Research Progress on Metal Substrates for YBa2Cu3O7-xCoated Conductor

摘要:

目前，低成本、高性能的YBa2Cu3O7-x涂层导体制备技术已成为国际实用化高温超导材料的研究重点。由于金属基带的特性(织构、表面粗糙度等)直接决定了阻隔层的特性，进而影响到YBCO层的超导性能。因此，制备高质量的金属基带是涂层导体制备技术的关键核心技术之一。本研究对金属基带的性能、选材、制备技术以及国内外的研究状况给予了较系统的总结和评述，并对其发展和应用前景进行了一些探讨

Abstract:

Fabrication techniques of low-cost high performance YBa2Cu3O7-x Coated Conductor have became the focus of practicable high temperature superconductor research, because the characteristics of metal substrates(texture, roughness of surface and so on) directly determine the characteristics of buffer layes, and further influence the superconducting performance of YBa2Cu3O7-x layer. Therefore, the preparation of high quality metal substrates is one of vital technologies for coated conductor. The performances, the choice of materials, preparation technology and the research status go of metal substrates at home and abroad are systematically summarized in the present paper. While the development and applicable prospects of metal substrates are also discussed.
