摘要
采用溶胶-凝胶法在经不同表面预处理的NiTi形状记忆合金(NiTi SMA)基体上复合锆钛酸铅(PZT)铁电陶瓷薄膜,利用X射线衍射仪和扫描电镜研究了烧结温度对复合材料的陶瓷层及NiTi SMA基体相组成的影响及NiTi SMA基体表面预处理形貌对其与陶瓷层之间复合结构的影响。结果表明:采用650℃烧结、缓慢冷却得到的陶瓷薄膜层具有单一钙钛矿PZT相结构;表面经过腐蚀预处理的NiTi SMA基体与陶瓷层结合良好。
PZT ferroelectric ceramic thin film was prepared on NiTi SMA substrate by sol-gel method. The effect of different surface states of NiTi SMA on combination between NiTi SMA and PZT ceramic thin film was studied by SEM . The effect of sintering temperature on phase compostion of ceramic thin film and NiTi SMA substrate was studied by XRD. The results show that the ceramic thin film possesse a single perovskite phase-PZT under the condition of sintering at 650 ℃. NiTi SMA with eroded surface has the best combination with the ceramic thin film.
