Description:
The cavitation erosion researches conducted on vibratory devices presents a way of degradation very similar with those encountered in industrial equipment. Photos of the cavitation cloud as well as the eroded surfaces, at various exposure periods, are the basis of the present work in the description of this destruction mechanism. For the experiments, there were used two materials: gray cast iron with lamellar graphite and a high resistance bronze. The used device is that of the Timisoara Polytechnic University Cavitation Laboratory which respects integrally the prescriptions of ASTM G32-2010 Standards. For the description of the results there are used both the roughness profiles and the structure images of the eroded areas, after four different exposure times (5, 60, 120 and 165 minutes). The cavitation erosion behavior is expressed both by the mean depth erosion (MDE) and the parameters of roughness values of the affected areas. The conclusion show that the specific degradation...
