日本藤仓公司与超导技术研究所合作开发成功高速制造超导线材新技术,每小时可生产超导线材约10米,制造速度比过去提高约20倍。 藤仓公司提供的资料说,这种高温超导线材由多晶耐热合金、中间层、钇超导体层及保护层构成。该公司改良了其10年前发明的取向中间层成膜技术—IBAD法,使用更高取向性的黄绿石型氧化物代替原来的锆氧化物制作中间层,用低能离子束在无取向性的合金线 Fujikura Co., Ltd. and Japan Institute of superconducting technology to develop successful high-speed manufacturing of high-speed wire new technology, superconducting wire can produce about 10 meters per hour, manufacturing speed increased by about 20 times in the past. Fujikura provided the information provided by the company, said high-temperature superconducting wire by the polycrystalline heat-resistant alloy, the middle layer, yttrium superconductor layer and the protective layer. The company improved its 10 years ago invented the orientation of the middle layer film-forming technology-IBAD method, the use of higher orientation of the pyrochlore oxide instead of the original zirconium oxide intermediate layer, using low-energy ion beam in the non-oriented alloy line
