摘　　要：铝阳极氧化膜在不同封孔溶液中封闭后,其使用寿命和耐蚀性会各不相同。采用了磷铬酸失重法、电化学极化曲线法、交流阻抗法研究了铝合金阳极氧化膜在氟锆酸钾、HX-588封闭剂、钼酸钠、亚硝酸钠和纯水的高温水溶液封闭后的耐蚀性,比较其间的差异,并找出其变化规律,反映出五种溶液的封闭效果。数据表明:封闭效果优劣排序依次为HX-588封闭剂、氟锆酸钾、钼酸钠、亚硝酸钠、纯水。说明氟锆酸钾可以作为一种绿色无镍封孔剂进行工业生产。The service life and corrosion resistance of sealed Aluminum anodic oxide film in different hole sealing solution will be different. The corrosion resistance of the sealed Aluminum oxide film in Zirconium fluoride acid potassium,HX-588 sealing agent,sodium molybdate,sodium nitrite and pure water of high temperature solution were studied by phosphorus-chromium acid weight-loss method and electrochemical polarization-curve method,electrochemical impedance spectros-copy,compare their differences and find out its change rule,reflects the sealing effect of 5 kinds of solution. The statistic shows that the sequence of sealing effect from excellent is HX-588 sealants,zirconium fluoride acid potassium,sodium mo-lybdate,sodium nitrite,pure water. That zirconium fluoride potassium can serve as a kind of green and nickel hole sealing a-gent for industrial production.
