摘    要：研究了70Cu-30Ni合金固溶处理后不同程度形变及其在NaCl溶液浸泡和海水暴 露中的腐蚀行为。结果表明，随着形变量增加，70Cu-30Ni合金腐蚀电位和极化电阻随时间下降速度增加，其腐蚀产物膜中镍含量增加，氯离子浓度减小，所形成的海水腐蚀产物膜薄。

Abstract: After solution treatment, 70Cu-30Ni alloys were deformed to different degrees and then immersed in NaCl solution and in seawater. The results show that with the increase of deformation and immersion time, corrosion potential and polarized resistance of 70Cu-30Ni alloys decrease more, and Ni content in creases and Cl^- decreases in the corrosion product films. With the increase of deformation, the corrosion product films of the alloys in seawater become thinner.
