Although the factors that influence ultrasonic cavitation erosion in solid particle suspensions have been extensively studied, the role that solid particles play in the cavitation process remains poorly understood. The ultrasonic cavitation erosion of AISI 1045 carbon steel was studied in the presence of monodisperse silica particles (10–100 μm, 0.5–20 vol%) suspended in transformer oil. Based on our results, we propose an overview of the possible influencing mechanisms of particle addition for specific particle sizes and concentrations. Four major regimes, namely a viscosity-enhancing regime (V), a particle-impinging regime (I), a particle-shielding regime (S), and a nuclei-adding regime (A) are identified, and their dependence on suspended particle characteristics is analyzed. The VISA regimes, in essence, reflect the viscous and inertial effects of suspended particles, and the way in which particle–particle interactions and heterogeneous nucleation affect erosion. This regime-based framework provides a better understanding of the dominant factors controlling the erosive wear caused by cavitation in the presence of solid particles, and provides a guide for erosion prediction and prevention.

尽管已经广泛研究了影响固体颗粒悬浮液中超声空化腐蚀的因素，但对固体颗粒在空化过程中所起的作用仍然知之甚少。在悬浮在变压器油中的单分散二氧化硅颗粒（10–100μm，0.5–20 vol％）的情况下，研究了AISI 1045碳钢的超声空化腐蚀。根据我们的结果，我们建议对特定粒径和浓度的颗粒添加可能产生的影响机理进行概述。确定了四个主要机制，即增粘机制（V），粒子撞击机制（I），粒子屏蔽机制（S）和原子核添加机制（A），以及它们对悬浮粒子的依赖性特征进行分析。本质上，签证制度 反映了悬浮颗粒的粘性和惯性效应，以及颗粒间相互作用和异质成核作用对侵蚀的影响方式。这种基于体系的框架可以更好地理解控制存在固体颗粒时由气蚀引起的侵蚀磨损的主要因素，并为侵蚀的预测和预防提供指导。
