摘　　要：将乌铜作为阳极进行了电化学氧化着色实验,探究了电解质溶液的组成、阳极电流密度、着色时间等对乌铜表面的色彩和附着力的影响。实验表明:乌铜在60 g/L NaOH溶液中,温度为25℃,阳极电流密度为9 A/dm^(2)时,电化学氧化30 min后能得到附着力好的乌黑色着色膜。In this thesis,black copper was used as the anode for electrochemical oxidation coloring.The influence of electrolyte solution composition,anode current density and coloring time on the surface color and adhesive force of the black copper were explored.Experiments showed that a grey black coloring surface with good adhesive force was gotten after the black copper was electrolytic oxidized in 60 g/L NaOH solution at 9 A/dm~2 anode current density and 25 ℃ for 30 min.
