摘要
钇系高温超导涂层导体具备优异的超导性能,有广泛的应用前景,因此成为国际上的研究热点之一。近年来涂层导体长带的研制在日本和美国等国家取得了巨大进展,目前主要的技术路线为离子束辅助沉积(IBAD)和轧制辅助双轴织构基带(RABiTS)2种,其中IBAD技术路线的使用更为广泛而且产品性能处于领先地位。基于对上述2种技术路线进行的对比分析研究,介绍了目前世界范围内主要研究单位的进展情况,并对这2种技术路线在涂层导体结构的3个基本部分(金属基带、过渡层、超导层)的制备情况进行了具体对比分析。
The YBCO coated conductor is an important material for application of high temperature superconductors in the future because of its excellent superconductivity properties. Therefore, lots of efforts have been made to develop coated conductors all over the world, especially the tremendous progresses made by Japan, USA and other countries for fabrica- tion of coated conductor long tapes in recent years. There are two main technical routes to fabricate coated conductors, which are Ion Beam Assisted Deposition （IBAD） and Rolling Assisted Biaxial Textured Substrates （RABiTS）. IBAD was utilized more widely and has achieved better product performance. Comparative analysis of these two technical routes was carried out. The worldwide progresses were introduced, and the fabrication of three structural components （ i. e. metallic substrate, buffer layers and superconducting film） was discussed for comparison of the two routes.
