Studies on the electrolytic coloring of anodic oxidation film of aluminum alloys for golden color;

铝合金阳极氧化膜着金色的研究

New formula and technology for rapidly golden coloring of stainless steel were determined,emphasized on the effect of components on coloring quail ty,as well as the coloring mechanism of electrolysis was discussed.

通过试验确定了一种不锈钢电解法快速着金色溶液的配方和最佳工艺参数 :4 0 g/LK2 Cr2 O7,2 0 g/LMnSO4,2 0 g/L (NH4) 2 SO4,2 0 g/LH3 BO3 ,添加剂A 9～ 12 g/L、添加剂B 10 g/L ,电解电压 3～ 4V ,阳极电流密度0 。

The preparation principles,golden brightness and measurements of glossy fading resistance of copper-base simulant gold alloys are described.
