以 Cu-Se 系铜合金化学着色液为对象,通过检测着色膜层的颜色,观察着色膜的均匀性和表面形貌,研究了着色液 pH 值、着色温度、着色时间等工艺参数及抛光、除油、擦拭等着色前后处理方法对最终着色质量的影响。 研究结果表明:pH 值和着色温度对着色膜的颜色和均匀性影响显著,最佳 pH 值为 1 . 5 ~ 2 ,最佳着色温度为 20 ~ 30 ℃ ;着色时间对着色膜层的颜色影响显著,对均匀性没有影响,时间越长,膜层越趋于黑色。

The effects of processing parameters including pH, temperature, time, and processing methods including polishing, wiping on coloration quality were investigated by color testing, optical microscope and SEM test . The results show that coloration quality is influenced notably by pH and temperature, processing parameter with pH at 1 . 5 ~ 2 and temperature at 20 ℃ ~ 30 ℃ is the best one, moreover, the color of thin film become black and uniformity of thin film keep steady along with the coloring time increases.
