Effect of Temperature on Electrochemical Behavior of B30 Cu-Ni Alloy in Seawater

The effect of temperature on electorchemical behavior of B30 Cu-Ni alloy in seawater was studied by linear polarization,potentiodynamic polarization,electrochemical impedance spectroscopy and cyclic anodic polarization.It was shown that with the increase of temperature,the corrosion carrent of B30 Cu-Ni alloy in seawater inceased,the oxide film formed on the surface became unstable,the probability of pitting corrosion was evident.
