摘要
本次通过硼酸-硫酸阳极氧化工艺在纳米陶瓷铝合金表面制备氧化膜层,结果表明:经过硼酸-硫酸阳极氧化后,纳米陶瓷铝合金基体表面形成了一层连续且耐蚀的氧化膜,厚度1.51μm,氧化膜层经过336h的盐雾试验后,腐蚀点点数小于5个,阳极氧化后表面亲水性变好,氧化膜层与水性底漆具有良好的结合力,油漆附着力测试达到合格。
In this study,an oxidation film layer was prepared on the surface of nano ceramic aluminum alloy using the boric acid sulfuric acid anodizing process.The results showed that after the boric acid sulfuric acid anodizing,a continuous and corrosion-resistant oxide film with a thickness of 1.51μm was formed on the surface of the nano ceramic aluminum alloy matrix.After 336 h of salt spray test,the number of corrosion points in the oxide film layer was less than 5,and the surface hydrophilicity increased after anodizing.The oxidation film layer has good adhesion with the water-based primer,and the paint adhesion test meets the requirements.
