The paper presents model of formation of cavitation in liquids taking into account influence of temperature and phase transitions. Analysis of the proposed model allowed us to establish that the evaporation and condensation processes of cryogenic liquid at the boundary of the cavitation bubble are the main factor that determines the influence of temperature on cavitation. The established more than 2-times variation of optimal exposure intensities at a small temperature change (no more than 25 %) indicates the need to develop a more advanced, highly sensitive to changes in acoustic load system for automatic dosing of input energy and maintaining the optimal exposure intensity. Taking into account the results obtained will allow creating systems for monitoring the erosion strength of materials and coatings operating in cryogenic liquid media at low temperatures.
