铈盐封孔对6061铝合金阳极氧化膜耐蚀性的影响

铈盐封孔对6061铝合金阳极氧化膜耐蚀性的影响Effect of Cerium Salt Sealing on Corrosion Resistance of Anodic Oxide Film of 6061 Aluminum Alloy为提高6061铝合金阳极氧化膜的耐蚀性,利用铈盐溶液对其进行封孔处理。用电化学阻抗谱(EIS)和浸泡试验研究了不同工艺铈盐封孔后的氧化膜在质量分数3.5% NaCl溶液中的耐蚀性。同时,通过剥蚀试验对比研究了铈盐封孔与铝溶胶封孔和沸水封孔的效果。结果表明:氧化膜在30 ℃下铈盐封孔150 min可获得较好的耐蚀性;铈盐封孔氧化膜的耐蚀性略低于沸水封孔氧化膜的,但优于溶胶封孔氧化膜的。 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. 全文下载:
