| Popis: |
The article describes the maximum erosion efficiency of an acoustically enhanced pulsating water jet on CW004A copper surface. The copper surface was disintegrated at a traverse speed v = 0.1 mm.s−1, water pressure of 39 MPa and circular nozzle diameter of 1.321 mm. The effect of the PWJ on the copper surface was evaluated based on a surface topography evaluation using an optical profilometry and a scanning electron microscopy analysis. In the experimental investigation, it was found that a low traverse speed rate has destructive effects on the material with significant weight and volume loss of the material. Surface topography was characterized by a formation of protrusions, depressions and craters. Subsurface material failure of up to 200 µm was detected. |
