摘　　要：借助XRD、SEM研究了Sol-Gel法制备NiTiSMA/FC薄膜复合材料在650℃晶化退火处理后的界面结构.结果表明,陶瓷薄膜层的约束抑制了NiTiSMA基体的高温时效反应;由于NiTiSMA基体表面的高温氧化产生的TiO2过渡层,使NiTiSMA与铁电陶瓷两异质之间良好结合.A layer of ferroelectric ceramic thin film was prepared on NiTiSMA substrate by Sol-Gel method. The interface structure of NiTi/FC composite annealed at 650℃ was studied by XRD and SEM. The results show that ageing reaction in the NiTiSMA substrate is inhibited by restriction of ceramic thin film, and TiO2 transition layer formed with surface oxidation of NiTiSMA substrate combines best NiTiSMA with ferroelectric ceramic.
