為提高6061鋁合金陽極氧化膜的耐蝕性，利用鈰鹽溶液對其進行封孔處理。用電化學阻抗譜(EIS)和浸泡試驗研究了不同工藝鈰鹽封孔后的氧化膜在質量分數3.5% NaCl溶液中的耐蝕性。同時，通過剝蝕試驗對比研究了鈰鹽封孔與鋁溶膠封孔和沸水封孔的效果。

In order to improve the corrosion resistance of 6061 aluminum alloy, the anodic films were sealed with rare earth cerium salt solution. Electrochemical impedance spectroscopy (EIS) and immersing tests were used to study the corrosion behavior of the anodic films sealed in cerium salt solution with different parameters in 3.5 mass% NaCl solution. And the sealing effect of cerium salt was compared with that of sealing in aluminum sol and boiling water. The results show that the film sealing in cerium salt at 30 ℃ for 150 min presented relatively good corrosion resistance, although it was slightly inferior in corrosion resistance to the film sealed by boiling water, but it provided better corrosion resistance than that by the sol-gel method.
