Abstract : An explanation is sought for the erosion of rigid surfaces on impact with drops by cavitation phenomena. It is shown that even on a hypothesis based on the loading by cumulative microjets, the part played by cavitation phenomena for speeds greater than 30 meters per second is negligibly small. Experimental confirmation is given of the view that the erosion damage under such conditions is determined by the effect of discrete drops, and it is from this point that one should start, for example, in determining the erosion stability of working blades in the last stages of condensation steam turbines.
