Abstract	Cavitation erosion-corrosion (CE-C) behaviour of various copper alloys for ship propellers were investigated in sulphide-containing 3.5% NaCl solutions. Results indicate that the CE-C resistance remarkably decreases with increase in sulphide concentration for cast and friction stir processed nickel-aluminum bronzes. CE increases the current density by approximately two orders of magnitude and causes a positive potential shift when the sulphide concentration exceeds 50 ppm. The synergistic effect between CE and corrosion contributes greatly to CE-C degradation in sulphide solutions. However, the CE-C behaviour is insensitive to sulphide concentration for manganese-aluminum bronze and manganese brass. In all solutions, CE causes a positive potential shift and increases the current density by less than one order of magnitude. Mechanical attack dominates the CE-C damage.
