This study is related to the behavior of various copper-based alloys and electrolytic copper against cavitation corrosion. A test was designed using an ultrasound (US) bath to create cavitation conditions in artificial seawater environment and monitoring the corrosion response via the free corrosion potential. It was observed that the low-alloyed copper systems, including pure copper, do not respond significantly on the impact of US, while the higher alloyed systems, nickel aluminum bronze, NAB, and manganese aluminium bronze, MAB, exhibit a pronounced electrochemical response. Based on mixed potential theory, this fact is explained based on the roles of kinetics, mass transport, and protective layers.
