| Abstract: |
| 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. |
