| 首先介绍了目前空蚀的几种损伤机制，其中空化气泡以冲击波和微射流形式作用于材料表面，并导致损伤的机械作用占主要地位。在此基础上，总结归纳了影响海洋环境下金属材料空蚀的影响因素及相关研究进展，将因素按照环境外因与材料性质内因进行划分，系统分析了各种因素对空蚀损伤的作用趋势和机制，明确了各因素间存在协同效应。最后，提出了今后空蚀研究的发展方向，如调控温度、盐度等各种环境因素，进行空化气泡产生、长大、溃灭及能量释放过程的机制研究；也可以从材料性质入手，设计合成具有优良表面性能和力学性能的新材料等，对如何减少海洋工况下的空蚀损伤的科学研究和工程应用具有一定的参考和指导意义。 |

| This paper aims to firstly introduce several damage mechanisms of cavitation erosion, in which cavitation bubbles act on the material surface in the form of shock wave and microjet, and the mechanical action leading to damage plays a major role. On this basis, the influencing factors and related research progress of cavitation erosion of metal materials in marine environment are summarized, and the factors are divided into environmental external factors and material properties internal factors. The action trend and mechanism of various factors on cavitation erosion damage are systematically analyzed, and the synergistic effect among all factors is clarified. Finally, this paper puts forward the development direction of cavitation research in the future, such as the regulation of temperature, salinity and other environmental factorsas well as the mechanism research of cavitation bubble for generation, growth, collapse and energy release process. It is also possible to design and synthesize new materials with excellent surface and mechanical properties from the perspective of material properties, which has certain reference and guiding significance for scientific research and engineering application of how to reduce cavitation damage under marine conditions. |
