摘要:
为了改善铝合金表面耐腐蚀性能和抗污染性能，采用阳极氧化工艺对铝合金预先表面处理，然后通过氟钛酸铵封孔使其具有光催化活性。表征了不同类型铝合金试样的微观形貌和表面成分，并测试了表面水滴接触角、极化曲线以及对亚甲基蓝的降解率。结果表明：阳极氧化后铝合金表面仍然呈亲水性且无光催化活性，抗污染性能较差。氟钛酸铵封孔反应产物可以封堵微孔提高阳极氧化膜的致密性，并且使铝合金表面具有疏水特性和光催化活性，能够隔离腐蚀介质延缓腐蚀发展，同时在光催化作用下降解有机污染物，从而改善铝合金表面耐腐蚀性能和抗污染性能。
Abstract:
： Aluminum alloy was treated by anodic oxidation and then sealed with ammonium fluorotitanate having photocatalytic activity in order to improve its surface corrosion resistance and antifouling property. The microstructure and surface components of different types of aluminum alloy sample were characterized ， and the contact angle of water droplet ， polarization curves and degradation rate to methylene blue were also tested. The results showed that the aluminum alloy after anodic oxidation still present hydrophilicity and has no photocatalytic activity ， and its antifouling property was poor. The reaction products generated during sealing with ammonium fluorotitanate can fill micropores and improve the compactness of anodic oxide film ， and make aluminum alloy having hydrophobic property and photocatalytic activity. It can isolate the corrosive medium and delay the corrosion development ， and degrade the organic pollutants under photocatalytic action ， thus improve surface corrosion resistance and antifouling property of aluminum alloy.
