我们详细报告了苏南的反应共蒸发沉积和反应（RCE-DR）过程。我们已经成功地制造了一个高性能的GdBCO涂层导体（CC）与高吞吐量的RCE-DR过程，包括两个步骤的元素金属氧化物的沉积和阳离子氧化物转化成GdBCO超导相。首先在低温和低压下在LaMnO 3（LMO）缓冲的IBAD-MgO模板上沉积构成金属如Gd、Ba和Cu，然后在高氧分压下进行高温处理步骤以进行快速相转化。由RCE-DR制造的GdBCO CC表现出优异的输运性能，如在77 K的自场的临界电流为794 A cm-1宽度。随着RCE-DR过程中，我们已经实现了超过120 m h-1（在一个真实的过程线性磁带速度等效）的整体处理速度。与之前开发的第二代高温超导线材的其他方法相比，苏南的RCE-DR技术作为最高产量的制造工艺显示出巨大的潜力，在价格和生产速度方面满足了当前和未来的行业需求。
We report in detail on SuNAM's reactive co-evaporation by deposition and reaction (RCE-DR) process. We have successfully fabricated a high performance GdBCO coated conductor (CC) with high throughput by the RCE-DR process, that consists of two steps for the deposition of elemental metal oxides and the conversion of cation oxides into the GdBCO superconducting phase. Constituting metals such as Gd, Ba and Cu were first deposited on LaMnO3 (LMO) -buffered IBAD-MgO templates at low temperatures and low pressures followed by a high temperature treatment step under high oxygen partial pressure for fast phase conversion. GdBCO CCs fabricated by RCE-DR showed excellent transport properties such as a critical current of 794 A cm 1 width at 77 K in self-field. With the RCE-DR process, we have achieved an overall processing speed of more than 120 m h 1 (in terms of a real process linear tape speed equivalent). SuNAM's RCE-DR technique showed great potential as the highest throughput fabrication process compared with other methods developed previously for second generation high temperature superconducting wires, meeting the current and future need of industry in terms of price and production speed.
