This paper analyzes the formation of cavitation damages depending on the technology of
fabrication, structure and properties of basalt from the Vrelo-Kopaonik deposit. The methodology for
monitoring the level of damage caused by cavitation and estimation the material life span base on
parameters was developed: change in the mass loss, measurement the degradation level of the sample
surface, dynamics of the formation ofpits, changes in their average area surface, determination the line
profile. A change in the surface morphology with the test time was followed by a scanning electron
microscopy. The level of surface degradation of samples was quantified using the image analysis. The
results indicate that the cast basalt has a high degree of cavitation resistance.
