摘要:
本文通过梳理铝合金零件铬酸阳极化工艺流程，采用故障树图对零件外观出现色差的原因进行了分析讨论。结果表明，同类材料、同种加工表面状态的铝合金零件经过铬酸阳极化后，互相之间的色差根源在于后处理填充槽液浓度的不合理。通过规范填充槽液管理，可有效消除铬酸阳极化膜层存在的色差问题。
Abstract:
In this paper, the process flow of chromic acid anodization for aluminium alloy parts was carded, and the cause of color difference in the appearance of parts was analyzed and discussed by using fault tree diagram. The results showed that the color difference between aluminium alloy parts with the same material and the same machined surface state after chromic acid anodization was due to the unreasonable concentration of filling bath in the post-processing. The color difference of chromic acid anodized film layer could be eliminated by the standardized management of filling tank liquor. The problem of color difference in chromic acid anodic film could be effectively eliminated by standardizing the management of filling bath liquid.
