To find a useful method for monitoring cavitation erosion arising in turbomachinery, several methods have been compared. There are mainly four typical methods : pure Al plate, soft Al foil, pressure-sensitive film and painting methods. However, the mutual relationship among them is yet unsettled. In this paper, therefore, the erosive area, where the erosion mainly takes place, was precisely detected by means of the four methods under the same flow conditions in typical separated flows around a slot. It was found that a large difference between the erosive areas is recognized, especially from the threshold levels, since each method inevitably has such an inherent characteristic threshold level against cavitation attacks.
