| 摘 要： | 探索了新的不含有害物质的铝合金阳极氧化膜绿色封闭技术;新方法使用了铈盐化学处理和钼盐溶液电化学处理相结合的工艺。对比了不同封闭方法对L3铝合金阳极氧化膜在NaCl溶液中耐蚀性的影响,包括氟化镍封闭,重铬酸钾封闭和铈-钼盐封闭。利用动电位极化法研究了封闭后阳极氧化膜的腐蚀行为。利用扫描电子显微镜(SEM)观察了封闭后阳极氧化膜的表面形貌和成分。结果表明铈-钼盐封闭工艺可以为铝合金阳极氧化膜在NaCl溶液中提供较高的耐蚀性。

| Abstract: | A green sealing method of anodic films on aluminum alloy L3 was studied to eliminate the toxic materials.The new process uses chemical treatments in cerium solution and an electrochemical treatment in a molybdate solution.Potentiodynamic polarization was used to study the influences of sealing methods on the corrosion behavior of anodic films in NaCl solutions.The Ce-Mo sealing made the surface structure and morphology of anodic films uniform and compact.Ce and Mo produced a cooperative effect to improve the corrosion resistance of anodic films.Anodic films sealed by Ce-Mo provided high corrosion resistance in NaCl solutions. |
