在双轴织构的Ni-5％W合金基带上,采用高分子辅助化学溶液沉积法通过提拉涂敷法,制备了厚度达250 nm的Sm0.2Ce0.8O1.9(SCO)外延织构单层缓冲层.通过严格控制前驱溶液的浓度、提拉速度、成相温度和热处理时间,所获的SCO单层缓冲层涂层平整、无微裂纹、且具有较强的(200)c轴外延织构.在其他条件假设不变的情况下,主要研究不同提拉速度对SCO缓冲层薄膜性能的影响.在此基础上,采用化学溶液法在SCO/NiW缓冲层上制备了YBCO超导层,其具有高度的双轴织构和均匀的表面形貌.结果表明:用提拉法获得的SCO单层缓冲层在具有适度的厚度下,仍然具有很好的织构传递特性,为低层本制造YBCO涂层导体长带提供了一条可靠的路线.
