Corrosion rates and the nature of corrosive attack were investigated for several high-damping alloys, including alloys based on the Cu-Mn, Fe-Cr-Al, Fe-Cr-Mo, Ti-Ni, and Cu-Zn-Al systems. Rates and modes of attack were determined for exposure of samples in synthetic and natural seawater. The results of potentiodynamic polarization and polarization resistance measurements made in the laboratory were compared with the results of actual sea exposures at the LaQue Center for Corrosion Technology, Wrightsville Beach, North Carolina. These results were used to make tentative recommendations with common aluminum alloys and steels in a marine environment. Overlays of independently determined potentiodynamic polarization plots for selected pairs of alloys were used to project theoretical corrosion rates in galvanic couples.
