泡沫铝阳极氧化工艺研究

Study on Anode oxidation process of foaming aluminium

介绍泡沫铝阳极氧化工艺。通过试验分析对比WL-SY酸蚀工艺和碱蚀工艺的差异,探讨泡沫铝阳极氧化过程中硫酸浓度、电流密度、温度、Al3+浓度、时间、杂质元素对阳极氧化膜的影响。

The anodic oxide process of foaming aluminium has been introduced. The difference of WL-SY acid corrosion is analyzed to compare with alkali corrosion by test. The effect of sulpharic acid concentration, electric current density, temperature, Al^3＋ ion concentration, time, foreign matter element on anode oxidation process of foaming aluminium are discussed.
