介绍了金属包覆超声缓冲棒的制备、表征和超声测试。芯和包层分别由锡/铅合金和纯锡组成，通过垂直连续铸造技术生产。使用225 MHz线聚焦光束扫描声学显微镜测量棒直径上的声速分布。纹影可视化系统证实了核心中声能的集中。在杆的末端制作了球形声透镜。已获得频率在2至10 MHz之间的聚焦和非聚焦超声测量以及具有优异信噪比的信号。
The fabrication, characterization, and ultrasonic measurements of clad metallic ultrasonic buffer rods are presented. The core and the cladding consist of tin/lead alloy and pure tin, respectively, produced by a vertical continuous casting technique. The acoustic velocity profiles across the rod diameter are measured using a 225‐MHz line focus beam scanning acoustic microscope. A schlieren visualization system confirms the concentration of acoustic energy in the core. Spherical acoustic lenses have been fabricated at the ends of the rods. Focused and unfocused ultrasonic measurements at frequencies between 2 to 10 MHz and signals with excellent signal to noise ratios have been obtained.
