本文报道了第二代Y1 Ba 2Cu 3 O 7-delta（YBCO）涂层导体的发展，该涂层导体沉积在使用离子束辅助沉积（IBAD）制造的双轴织构MgO模板上。描述了用于在柔性高温合金衬底上实现高临界超电流的材料体系结构和加工技术。在金属衬底上的YBCO薄膜的织构接近于在单晶氧化物衬底上沉积的薄膜的织构。金属衬底上YBCO薄膜的临界电流和临界电流密度也与单晶氧化物上YBCO薄膜相当。
This article reports on the development of second-generation Y1Ba2Cu3O7-delta (YBCO)-coated conductors deposited on biaxially textured MgO templates fabricated using ion-beam-assisted deposition (IBAD). The materials system architecture and processing techniques used to achieve high critical supercurrents on flexible superalloy substrates is described. The texturing of YBCO films on metal substrates approaches that of films deposited on single-crystal oxide substrates. Critical currents and critical current densities of YBCO films on metal substrates are also equivalent to YBCO films deposited on single-crystal oxides.
