机械表面改性，如喷丸处理，可有效提高金属和其他材料的疲劳性能。在水力机械中，空化通常会造成表面损伤。然而，通过仔细选择工艺参数，可以开发出一种称为“空化强化”的方法。它的优点是表面粗糙度增加比传统喷丸低，因为不涉及固体碰撞。由于空化是一种流体动力学现象，因此需要对流体力学和材料科学有所了解。空化喷丸不同于使用水柱冲量的“水射流喷丸”。另一种方法是“水下激光喷丸”，它涉及到脉冲激光的使用，可以被认为是一种空化喷丸，由于激光消融而产生空化气泡。超声波振动是一种流行的产生空化清洗的方法，也被用于空化喷丸。本文根据水射流、脉冲激光和超声空化喷丸的已报道数据，对空化喷丸的机理进行了分析，提出了发展空化喷丸技术所需的主要观点和成果，并指出了今后的发展方向。通过与喷丸处理的比较，对数据和方法进行了认真的考虑和总结。提出了未来挑战的战略观点。
Mechanical surface modification such as shot peening offer powerful enhancement of fatigue properties of metals and other materials. Cavitation usually causes surface damage in hydraulic machineries. However, careful selection of process parameters allowed developing an approach known as “cavitation peening.” Its advantage is surface roughness increase is lower than in conventional shot peening as there are no solid collisions involved. As cavitation is a hydrodynamic phenomenon, an understanding of both fluid dynamics and materials science is required. Cavitation peening is distinguished from “water jet peening,” in which water column impulse is used. Another flavor is “Submerged laser peening” that involves the use of a pulsed laser and can be considered a type of cavitation peening where cavitating bubbles are generated due to laser ablation. Ultrasound vibration, a popular method for generating cavitation for cleaning, has also been adapted for cavitation peening. The present comparative review presents key insights and achievements and addresses future directions that are required for advancing cavitation peening technology by considering the mechanisms of cavitation peening based on the reported data for water jet, pulsed laser, and ultrasonic cavitation peening. The data and methods are critically considered and summarized in comparison with shot peening. Strategic view of future challenges is presented.
