摘要:
为了进一步改善建筑铝材表面阳极氧化膜的腐蚀防护性能，在电解液中添加稀土盐 - 硫酸铈，并研究了硫酸铈质量浓度对阳极氧化膜的微观形貌、厚度和腐蚀防护性能的影响。结果表明：随着硫酸铈质量浓度从 0 g/L 增加到 0.6 g/L ，阳极氧化膜的孔隙率明显降低，致密性得到改善，并且厚度呈增加的趋势，对建筑铝材的腐蚀防护性能逐渐提高。但随着硫酸铈质量浓度从 0.6 g/L 继续增加到 1.2 g/L ，阳极氧化膜的孔隙率升高，致密性和厚度都降低，导致腐蚀防护性能下降。当硫酸铈质量浓度为 0.6 g/L 时，阳极氧化膜的孔隙率仅为 14.5% ，其致密性良好而且较厚，对建筑铝材具有良好的腐蚀防护作用。
Abstract:
： In order to improve the corrosion protection of anodic oxidation film on surface of construction aluminum ， the rare earth salt ， cerium sulfate ， was added into the electrolyte ， and the effect of the mass concentration of cerium sulfate on the microstructure ， thickness and corrosion protection of anodic oxidation film was studied. The results showed that as the mass concentration of cerium sulfate increases from 0 g/L to 0.6 g/L ， the porosity of anodic oxidation film is obviously reduced ， and the corrosion protection of anodic oxidation film to construction aluminum is improved due to the increasing of thickness and improvement of the compactness. However ， as the mass concentration of cerium sulfate is increased from 0.6 g/L to 1.2 g/L ， the porosity of anodic oxidation film is increased and both the compactness and thickness decrease ， leading to the deterioration of corrosion protection to construction aluminum. When the mass concentration of cerium sulfate is 0.6 g/L ， the anodic oxidation film is thicker and denser with a porosity of only 14.5% ， so it can offer good corrosion protection effect on construction aluminum.
