The paper describes the interaction between pulsating water jet and surface of three different metals: 316L stainless steel, 6068 Al alloy and Ti6Al4V Ti alloy. The pulsating water jet is formed by using the ultrasonic sonotrode to the pressurized acoustic water chamber. It appears that the shape of the resulting water jet differs at various distances from the nozzle and the state of the surface of tested materials treated by the jet at various standoff distances differs very substantially. Moreover, the three materials are exposed to pulsating water jet at different standoff distances and results are discussed in terms of the capacity to absorb plastic deformation. As expected, at optimal standoff distance, the deepest eroded path appears in the Al alloy and the most resistant material is the Ti alloy.
