A material-damaging process which occurs as a result of vaporous cavitation. 'Cavitation' refers to the occurrence or formation of gas- or vapor- filled pockets in flowing liquids due to the hydrodynamic generation of low pressure (below atmospheric pressure). This damage results from the hammering action when cavitation bubbles implode in the flow stream. Ultra- high pressures caused by the collapse of the vapor bubbles produce deformation, material failure and, finally, erosion of the surfaces.
