在工业应用中，高应力的轴系部件如果没有进行表面处理，很容易因循环载荷而损坏。通过使用超声波空化喷丸，可以提高这些部件的残余压应力和表面硬度。传统的纵向振动换能器用于处理圆柱形工件，但处理面积有限，且处理周期较长。为了解决这些问题，我们设计了一种新颖的压电换能器结构，即杆和环组合的类型。在超声空化喷丸过程中，我们将圆柱形工件放置在环形工具中以改善限制。然而，处理后的表面性能很大程度上受输入参数（驱动电压和棒直径）的影响。在这项研究中，首先对覆盖有铝箔的圆柱形工件进行超声波空化喷丸处理，以检测处理表面上空化气泡的强度和分布。然后，利用声化学发光方法作为寻找最佳操作参数（190 V 和 16 mm）的附加方法。最后，以最佳参数进行超声空化过程。处理结果表明，表面硬度提高约36%，而表面粗糙度没有明显增加。
In industrial applications, the shafting components with high stress are easily damaged due to cyclic loads if there is no surface treatment. With the use of ultrasonic cavitation peening, the residual compressive stress and the surface hardness of these components can be improved. While traditional longitudinal vibration transducers are used to treat cylindrical workpieces, the treated areas are limited, and the treatment period is relatively long. To solve these problems, we designed a novel configuration of the piezoelectric transducer as a type of the combination of rod and ring. During ultrasonic cavitation peening, we placed the cylindrical workpieces in the ring tool to improve the limitation. However, the treated surface properties were largely influenced by the input parameters (driving voltage and rod diameters). In this investigation, the cylindrical workpieces, which were covered with aluminum foils, were first treated by ultrasonic cavitation peening to detect the intensity and distribution of the cavitation bubbles on the treated surface. Then, the sonochemiluminescence method was utilized as an additional way to find the optimal operation parameters (190 V and 16 mm). Finally, the ultrasonic cavitation process was conducted with the optimal parameters. The treatment results showed that the surface hardness increased by about 36% without significant increase of the surface roughness.
