摘要
研究 Ni2 + 、Fe3+ 、Na+ 、K+ 、PO3- 4、C2 O2 - 4、Cr2 O2 - 7、S2 O2 - 8和 SO2 - 3等不同离子和有机物对铝合金氧化膜的作用 .结果表明 ,在基液中添加阳离子、阴离子和有机物 (酒石酸 ,柠檬酸 ,苹果酸等 )对氧化膜厚度和硬度都有不同程度的提高 ,有机物的作用尤其显著 ,而三者的组合可作为铝合金阳极氧化宽温添加剂 .电镜结果显示 ,3 5℃下硫酸基液中形成的氧化膜松散而不致密 ,氧化膜厚度和硬度都较低 ,而加入宽温添加剂于硫酸基液中 ,由于宽温添加剂有减缓氧化膜溶解的作用 。
The effects of cations, anions and organic substances on the structure and property of oxidation films of Al alloy have been investigated. The results showed that the thickness and hardness of the oxidation films can be increased by adding the additives at 35 ℃. The mixture or complex of the above substances can be as complicated additives for oxidation film of Al alloy at medium temperature. The structure of oxidation film formed at 35 ℃ with complicated additives was fine and close in texture. The property of oxidation film of Al alloy in the solution with organic substance additives is the best and that with cation additives is the worst.
