Abstract
An experimental study was done on the relation between the positions of specimen and erosion-corrosion behavior of aluminum alloy exposed to the two phase jet flow with high temperature of 388K and high speed of 177m/s as the variable of the volume flowrate ratio β of liquid to the sum of liquid and steam. The damage rate, pit diameter and pit depth of aluminum alloy were maximum at β=2×10-3, in the case that the jet impinged perpendicularly to the specimen surface on which the liquid film was thin. When the specimen was set parallel to the flow, the corrosion rate was increased due to local turbulent flows on the surface, but the corrosion rate without such a flow was a little at the same rate as that in the still liquid.
