摘　　要：本文用横形电解槽对铝阳极氧化膜在镍盐溶液中交流电解着色的电流分布作了较详细的研究,结果表明:着色的电流密度与表示颜色深浅程度的值随极间距的增大而减小,随试片面积与对碳极面积的比值减小而增大;试片着色重叠屏蔽效应很强,分散能力不好;电极导电的接触点数目与位置对着色无影响。Current distribution in Ac electrolytic coloring of Al anodizing oxidation film in Ni salt solution by lateral arranged electrolytic thank is studied in detail. Results show: 1.the curret density for coloring and the value indicating color shades decrease with the increase of electrode distance, and increase with the decrease of the area ratio of test plate to carbon electrode; 2. the effect of superimposed shield for sample coloring is strong and the throwing power is not good; 3. the number and location of the contacts for electrode conduction have no effect on dyeing.
