摘要:

    釔系高溫超導(dǎo)涂層導(dǎo)體具備優(yōu)異的超導(dǎo)性能，有廣泛的應(yīng)用前景，因此成為國(guó)際上的研究熱點(diǎn)之一。近年來涂層導(dǎo)體長(zhǎng)帶的研制在日本和美國(guó)等國(guó)家取得了巨大進(jìn)展，目前主要的技術(shù)路線為離子束輔助沉積（IBAD）和軋制輔助雙軸織構(gòu)基帶（RABiTS）2種，其中IBAD技術(shù)路線的使用更為廣泛而且產(chǎn)品性能處于領(lǐng)先地位。基于對(duì)上述2種技術(shù)路線進(jìn)行的對(duì)比分析研究，介紹了目前世界范圍內(nèi)主要研究單位的進(jìn)展情況，并對(duì)這2種技術(shù)路線在涂層導(dǎo)體結(jié)構(gòu)的3個(gè)基本部分（金屬基帶、過渡層、超導(dǎo)層）的制備情況進(jìn)行了具體對(duì)比分析。��

Abstract:

     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 fabrication 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 (ie metallic substrate, buffer layers and superconducting film) was discussed for comparison of the two routes.��
