沉积不连续NiTi形状记忆合金薄膜PZT的阻尼性能
Damping Capacity of PZT Deposited Discontinuous NiTi SMA Thin Film
摘 要
在铁电陶瓷锆钛酸铅(PZT)表面沉积不连续的NiTi形状记忆合金(SMA)薄膜, 运用XRD、SEM 和动态弹性模量测试仪研究了其显微组织及阻尼特性。结果表明:与PZT 相比, NiTi SMA 薄膜/PZT复合材料的阻尼性能下降;原因是PZT 基体与NiTiSMA 薄膜在晶化冷却时的收缩不一致导致在PZT基体中靠近薄膜的区域形成了组织异常区, 限制了电偶极子的运动, 在外界应力作用下薄膜与基体两者的应变不协调加强了异常区对电偶极子运动的限制。

Abstract
The discontinuous NiTi shape memory alloy (SMA) film was deposited on PZT surface. The micro structure and damping capacities of the material had been studied by using XRD, SEM and dynamic elastic modulus tester. The results show that the damping capacity of the composite of NiTi SMA film/PZT decreased comparing with PZT. The reason was that the in consistent contraction of NiTi SMA film and PZT matrix during crystallization cooling formed a structure anomalous area in the PZT matrix near the film, which limited the movement of electric dipole. Under the in fluence of outside stress, the harmonious strain between thin film and matrix strengthened the limiting of the anomalous area on electric dipole movement.
