Abstract : The interacting influence of corrosion on cavitation damage was studied quantitatively using a magnetostrictive device. The relationship between the rate of weight loss and the amplitude of oscillation for 1020 mild steel became modified as the NaC1 concentration was increased. When 1100-F aluminum was used, this relationship was not affected. An attempt was made to estimate the contribution of electrochemical corrosion to total damage by means of (1) static polarization measurements, (2) dynamic polarization measurements, (3) short-duration pulsing technique, and (4) long duration pulsing technique.
