铝合金的腐蚀路径

研究AA2024-T3、AA5083-O和AA6082-T6合金的腐蚀路径,以进一步了解铝合金局部腐蚀机理。采用扫插电子显微镜研究合金在3.5% NaCl溶液中动电位极化测试后腐蚀表面,利用扫描振动电极技术分析阳极电解液的流动。结果表明:各合金的腐蚀路径明显不同,且受阳极电解液流动的影响。另外,在AA5083-O和AA6082合金中,腐蚀以两种方式进行扩展:一种为腐蚀前端扩展路径(AA5083的丝状扩展路径和AA6082合金有条理的线性扩散路径);另一种为沿á100?方向的晶体学通道扩展路径。与AA2024-T3合金相比,AA5083-O和AA6082-T6合金的扩展路径与晶粒特征有关,而与粗大的第二相粒子无关。而 AA2024-T3的扩展路径与第二相粒子和晶界特征有关。
