The paper presents an evaluation of 17 materials produced in Poland as to their cavitation resistance. In the paper new factor of cavitation erosion resistance of materials, representing some results from whole erosion test is proposed. New coefficient of cavitation erosion resistance R is a function of the incubation time, maximum volume loss rate vmax and time replying of vmax rate. This factor has been referred to the mean durability qcav, representing the results of the whole erosion test. The results indicate that there is very good correlation between cavitation erosion resistance represented by factor R and mean durability qcav.
