Abstract : The cavitation attack can cause various damages of the material, depending on cavitation intensity. Herein the relationships between cavitation intensity and the changes of microstructure of aluminium-magnesium alloy are presented. Correlation between energy flux density and mass erosion rate is de-scribed by simple empirical mathematical expression: ER = 1E – 05 J 2 + 0,0005 J, where: J – energy flux density, ER – cavitation erosion rate. Here it is shown that for the intensity of cavitation J<2 mW/m2 the duration of the incubation period is invariable, while at the cavitation intensity J>1 mW/m2 its duration decreases with increasing energy flux density J.
