| Abstract | Piezoelectric thick (>66µm) films have been directly coated onto aluminum (Al) substrates using a sol-gel spray technique. With a top electrode these films serve as integrated ultrasonic transducers (IUTs) which normally operate as thickness vibration longitudinal wave transducers. When such IUTs are located at the edges of the metallic plates, they can excite and detect symmetrical, anti-symmetric and shear horizontal types of PAWs using mode conversion methods. In 2mm thick Al plates two line defects of 1mm width and 1mm depth were clearly detected at temperatures up to 150°C in pulse-echo mode. Results indicated that for 2mm thick aluminum plates shear horizontal PAWs were the best for the line defect detection. Also the experimental results agree well with those obtained by a finite difference based method. |
