An experimental method is described for the electrochemical and visual monitoring of erosion-corrosion of copper and copper-nickel alloys in a synthetic sea water environment. An impinging jet cell was designed to accommodate electrochemical instrumentation and video microscopy equipment. A combination of electrochemical techniques including corrosion potential monitoring and impedance spectroscopy are utilized to investigate the state of the system and the reactivity of the electrode surface. Digital images of the electrode surface are acquired in-situ to provide a visual record of the events occurring on the electrode surface.
