摘　　要：采用线性极化、动电位极化、交流阻抗、循环阳极极化等测试方法,研究了温度变化对B30铜镍合金在海水中电化学行为的影响。结果表明:随着温度的升高,B30铜镍合金在海水中的腐蚀电流密度增大,生成的表面膜稳定性下降,点蚀倾向加重。The effect of temperature on electorchemical behavior of 1330 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 1330 Cu-Ni alloy in seawater inceased, the oxide film formed on the surface became unstable, the probability of pitting corrosion was evident.
