| Abstract: | The Cavitation erosion experimental process and results for three kinds of propeller alloys and a kind of brass are presented. The experimental facility is a rotating disk in water. The cavitation pattern on the disk and the changes in the weight loss, the rate of pit formation and the surface appearance of the specimens were measured respectively during the experimental process. The relations between the intensity of cavitation erosion, the resistance to cavitation damage and the mechanical properties of the experimental materials under the various speeds we re also examined. |
