    摘要:

    在雙軸織構(gòu)的Ni-5%W合金基帶上，采用高分子輔助化學(xué)溶液沉積法通過提拉涂敷法，制備了厚度達(dá)250 nm的Sm0.2Ce0.8O1.9（SCO）外延織構(gòu)單層緩沖層。通過嚴(yán)格控制前驅(qū)溶液的濃度、提拉速度、成相溫度和熱處理時間，所獲的SCO單層緩沖層涂層平整、無微裂紋、且具有較強(qiáng)的（200） c軸外延織構(gòu)。在其他條件假設(shè)不變的情況下，主要研究不同提拉速度對SCO緩沖層薄膜性能的影響。在此基礎(chǔ)上，采用化學(xué)溶液法在SCO/NiW緩沖層上制備了YBCO 超導(dǎo)層，其具有高度的雙軸織構(gòu)和均勻的表面形貌。結(jié)果表明：用提拉法獲得的SCO單層緩沖層在具有適度的厚度下，仍然具有很好的織構(gòu)傳遞特性，為低層本制造YBCO涂層導(dǎo)體長帶提供了一條可靠的路線。

    Abstract:

    An epitaxial Sm0.2Ce0.8O1.9-x (SCO) single buffer layer with thickness of about 250 nm has been deposited via dip-coating polymer-assisted chemical solution deposition (PACSD) approach for YBCO coated conductors on bi-axially textured Ni-5%W (200) alloy substrate. Flat, crack-free SCO films with sharp (200) c-axis orientation and texture have been obtained by carefully controlling the concentration of precursor solution, withdrawing speed, annealing temperature and dwelling time. Leaving other three factors unchanged, focuses on the influence of different withdrawing speeds on the performance of the SCO buffer layer has been focused on. YBCO superconducting layer has been deposited equally via dip-coating PACSD approach on the SCO-buffered NiW, showing a bi-axially texture. Micro-structural investigations revealed a homogeneous surface structure. Both of these indicate that SCO single buffer layer can function well as template. The approach has shown a promising way to fabricate long-length, low-cost YBCO coated conductors.
