摘 要: 研究了70Cu-30Ni合金固溶處理后不同程度形變及其在NaCl溶液浸泡和海水暴 露中的腐蝕行為。結(jié)果表明，隨著形變量增加，70Cu-30Ni合金腐蝕電位和極化電阻隨時間下降速度增加，其腐蝕產(chǎn)物膜中鎳含量增加，氯離子濃度減小，所形成的海水腐蝕產(chǎn)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.
Key words: 70Cu-30Ni alloy seawater corrosion deformation
