In this paper some results of cavitation erosion studies of various constructional steels (15GA, 15HN, 45, 2H13) processed superficially by laser beam are pre-sented. The erosion tests were carried out by using the rotation disk facility. Con-stant values of the erosion rate were found for each stage of the material damage. Proposition of the evaluation of the relative cavitation erosion resistance of laser processed materials in the incubation period of damage consisted in direct compar-ing of the constant rates of the erosion.
