将2024和2124铝合金与电位较正的钛合金（TC4）联接加速腐蚀，通过测试电偶腐蚀电流的分布曲线对比研究将铝合金经阳极化处理后的电偶腐蚀敏感性。采用表面形貌观察分析2×××系列铝合金的电偶腐蚀行为。结果表明，纯化可以减小材料的腐蚀电流密度和腐蚀电位，但效果不太明显，而阳极氧化处理可以明显降低其腐蚀敏感性，是防护电偶腐蚀的重要措施之一。
Galvanic corrosion sensitivity of 2024 and 2124 aluminum alloys connected with high potential titanium alloy (TC4) to speed up corrosion was compared to the anodized aluminum alloy by measuring the current distribution curves of galvanic corrosion. By observing the surface morphology after corrosion, the galvanic corrosion behavior of 2××× series Al Alloy was analyzed. The results showed that purification could slightly reduce the corrosion current density and corrosion potential. Anodization could reduce the sensitivity of the corrosion effect significantly, which was an important protective measure for galvanic corrosion.
