It has been shown that the premixed abrasive water jet has a greater capacity for drilling and cutting than the conventional abrasive water jet. In the present investigations, damage produced by the impingement of the premixed abrasive water jet at the jetting pressure of 11.9 MPa was experimentally studied with specimens of stainless steel. Two different aluminum oxides, # 100 and # 220, with grain size of 45 to 75 μm and l06 to 150 μm were used. The structure of the jet was observed through instantaneous photographs. The structure and the erosive properties of the jet are affected greatly by the grain size of the abrasive. The aspects of the time variations of mass loss and erosion pit depth at the optimum standoff distance were hardly affected by the grain size of the abrasive.
