采用浸泡试验、电化学试验、体视显微镜及扫描电子显微镜（SEM）观察等方法研究了A106B碳钢和304L不锈钢在含不同量Cu²⁺的人造海水溶液中的腐蚀行为。浸泡试验结果表明：随着Cu²⁺含量的升高，A106B碳钢的腐蚀速率升高，腐蚀形貌均表现为均匀腐蚀；304L不锈钢发生明显点蚀，且随着Cu²⁺含量的升高耐点蚀性能下降。电化学试验结果表明：随着Cu²⁺含量的升高，A106B碳钢的自腐蚀电位负移，当Cu²⁺含量升高到100 mg/L及以上时，极化曲线明显向右上方移动，即自腐蚀电位和自腐蚀电流密度均明显提高； 304L不锈钢的极化曲线向右上方移动，自腐蚀电位明显提高，钝化区范围缩短，点蚀敏感性提高。

The corrosion behaviors of A106B carbon steel and 304L stainless steel in artificial seawater solution containing different content of Cu²⁺ were studied by immersion test, electrochemical test, stereo microscopy and scanning electron microscopy (SEM) observation. The results of immersion test showed that with the increase of Cu²⁺ content, the corrosion rate of A106B carbon steel increased, and the corrosion morphology showed uniform corrosion. The 304L stainless steel had obvious pitting, and the pitting resistance decreased with the increase of Cu²⁺ content. The results of electrochemical tests showed that the self-corrosion potential of A106B carbon steel shifted negatively with the increase of Cu²⁺ content. When the Cu²⁺ content increased to 100 mg/L and above, the polarization curve shifted to the upper right, and both the self-corrosion potential and the self-corrosion current density were significantly increased. The polarization curve of 304L stainless steel moved to the upper right with the increase of Cu²⁺ content, the self-corrosion potential was obviously improved, the range of the passivation zone was shortened, and the pitting sensitivity increased.
