Commercialization of YBa₂Cu₃O₇₋ₓ (YBCO) superconducting coated conductor composite (CCC) technology requires a cost‑effective continuous manufacturing process. The conductor architecture consists of a metal‑organic‑derived YBCO layer coated on a deformation‑textured NiW alloy substrate buffered with Y₂O₃/YSZ/CeO₂. High‑critical‑current YBCO CCC wires with excellent uniformity were fabricated using an all‑continuous process, achieving 77 K self‑field critical currents up to 118 A in 1 cm‑wide tapes over 1.25 m lengths with a 3 % standard deviation, demonstrating feasibility of commercial long‑length CCC wire on deformation‑textured metal substrates and solution‑based YBCO deposition.
Commercialization of YBa/sub 2/Cu/sub 3/O/sub 7-x/ (YBCO) superconducting coated conductor composite (CCC) technology requires a cost-effective continuous manufacturing process. High critical current YBCO CCC wires with excellent uniformity over length have been fabricated using an all-continuous process. The conductor architecture consists of a metal organic derived YBCO layer, coated on a deformation-textured NiW alloy substrate buffered with Y/sub 2/O/sub 3//YSZ/CeO/sub 2/. Critical current at 77 K, self-field, of up to 118 A was achieved in 1 cm-wide tapes over 1.25 meter lengths, with a standard deviation of 3% measured on a 5 cm scale. The high uniformity and performance supports the feasibility of commercial long-length CCC wire based on deformation textured metal substrates and solution-based deposition of YBCO.
