The term "hard erosion" means erosion harder than ordinary erosion of two figures or more. We carefully observed the cavitation aspects of several types and the corresponding eroded surfaces in typically accelerating erosion tests on a typical material of 304 stainless steel by means of high-speed and SEM photography under a specified condition of uniform cavitation-nuclei-size distribution. The hard erosion is clearly resulted from the very high shock pressures accompanied by collapsing massive bubbles.
