Influence at Work Distance between the Sonotrode and Specimen to Cavitational Erosion

The paper presents the results of cavitation erosion tests performed on five samples from pure aluminum using the vibratory method with stationary specimen. The main purpose of this research is for determine which is the distance between the sonotrode and specimen favorable for an aggressive cavitational attack. For this, has been calculated the Mean Depth of Erosion (MDE) and the cavitation erosion rate (Vec). After that the specific curve for Vec has been analytically processed
