%X 为了缩短高温超导涂层导体缓冲层薄膜制备周期，采用自开发的前驱溶液，以乳酸为溶剂，硝酸钐和硝酸铋为溶质，在应由表面氧化外延法所得的衬底（NiO（l00）/NiW）上，用化学溶液沉积快速制备了SmBiO3缓冲层薄膜，研究成相温度对SmBiO3薄膜的影响；在SmBiO3薄膜上沉积YBa2Cu3O7-δ超导层，检验其效用. 研究结果表明：在798.5 ℃下制备的SmBiO3缓冲层薄膜平整致密，并且高度织构，缓冲层薄膜制备周期缩短到2 h以内；在SmBiO3上所沉积的超导层薄膜超导转变温度为89 K，超导临界电流密度为1.46 MA/cm2（77 K、0 T），达到了某些电力应用要求；该SmBiO3薄膜制备方法可用于高温超导涂层导体的快速制备.<br>： In order to shorten the preparation period of buffer layer for high-performance coated conductors, SmBiO3 (SBO) buffer films were efficiently deposited on surface-oxidation epitaxy processed NiO(100)/NiW substrates by chemical solution deposition (CSD) method, using a precursor solution prepared by dissolving samarium nitrate and bismuth nitrate precursors in lactic acid. The effect of sintering temperature on the SBO film was systematically studied. Then, the YBa2Cu3O7-δ (YBCO) superconductive film was deposited on the SBO buffer layer to test its utility. Results show that a highly textured, smooth and dense SBO thin film was obtained at 798.5 ℃, and the SBO thin film could be prepared within a period of less than 2 h. The YBCO superconductive layer was successfully deposited on the SBO layer with a superconducting transition temperature of 89 K and a critical current density of 1.46 MA/cm2 (77 K, 0 T), which could be used in some electric power applications. Therefore, the proposed method for preparing SBO buffer layer can be used for rapid preparation of coated conductors
