The article presents modern methods of cavitation erosion of metal and protection against cavitation, and considers safety issues.The general hypothesis of cavitation erosion, erosion of a material, the occurrence of cavitation erosion due to impact, the impact of a flow hitting the surface of a material and causing cavitation bubbles, a jet resulting from the explosion of bubbles hitting the surface of a material and bursting, and the occurrence of inertial force is considered.The patterns of erosion of steel material in a hydraulic structure are considered and graphs are obtained that describe the erosion of steel material using formulas or semi-empirical formulas expressing bending, shear, axial movement, stretching or compression of a sample of this material.Material as a result of the application of cyclic symmetrical forces.The microstructure of blocks has various variations.The structural characteristics of cavitation formed in cavities with small bubbles are presented; shock pulses are formed as a result of the merging of small air bubbles, and the occurrence of these shock pulses varies depending on the structure of the cavitation bubbles.The experimental results obtained using the example showed that the proposed method is more effective than the known ones.
