摘要
通过磁控溅射在锆钛酸铅陶瓷(PZT)基体表面沉积一定面积的NiTi SMA薄膜,用显微硬度测试分析薄膜与PZT基体间的结合力.结果表明:随沉积膜宽度增加,NiTi SMA薄膜与PZT基体的结合力减小;膜宽L<3mm的NiTi SMA薄膜,其膜基结合力最高达351N/mm^2,比膜宽L≥3mm的结合力高2倍多.
The NiTi SMA thin films were deposited on the surface of lead zirconate titanate ceramics （PZT） by magnetron sputtering, and the bonding properties between the films and PZT were analyzed by microhardness test. The results show that the bonding force of NiTi SMA film to PZT matrix is decreased with the increase of the width of the deposited film. The NiTi SMA film with film width L〈3 mm has a film-bound capacity of 351 N/mm2 , which is 2 times higher than film width L≥3 mm.
