An investigation of erosion-corrosion was carried out using an impingement jet apparatus and vibratory water bath. Obtained results were as follows: (1). The mass loss of the damaged material increased with the jet velocity in the range of V=0-0.5m/s, and got the largest at the velocity V=0.5m/s. Then the loss at V=1.5-6.0m/s became as small as that at V=0m/s. The mall loss was proportional to the area of damaged surface. (2) Pitting occurred in the surface of the target material number impingement jet flow. The diameter of a produced pit decreased with increasing the jet velocity, but the depth of the pit was independent on the velocity, (3) The oxidation number of the iron oxide of the corrosion products in the flow was relatively low. (4) The mass loss in pressure vibrating field is larger than that in a static field, and the damage pattern is unumiform compared with that in the static field.
