摘要：

This work was initiated primarily to investigate the reports that electrochemical measurements underestimate (by as much as an order of magnitude, or more) the corrosion rate of copper, nickel, or copper-nickel alloys in aqueous systems of near neutral pH. However, some consideration has also been given to the cause of corrosion rate overestimates. In this work, polarization resistance data for copper alloy 706 (90:10 Cu:Ni) and alloy 715 (70:30 Cu:Ni) in flowing seawater are analyzed and are shown to be consistent with measured weight losses if certain precautions are taken.
