Development and analysis of coatings cavitation erosion model by controlling changes in the acoustic properties of liquid media in limited volumes with resonant dimensions

The article considers the influence of the extent of cavitation wear of materials and their coatings on the acoustic properties of the sounded liquid media in a limited volume. The model of an liquid media bounded by a volume with resonant dimensions is considered based on an electromechanical analogy system. The parameters and characteristics of the sounded liquid media most sensitive to changes in the dimensions of the volumes confining them as a result of their cavitation erosion are determined.
