- 摘要:
- 对恒压与恒流铝阳极氧化两种控制方法的优缺点、不同点与相同点等进行了多方面比较。结果表明:恒压控制主要优点是操作简便、少数工件出现导电不良对其余工件影响较小,但在工艺条件波动较大的情况下,会出现较大的膜厚偏差。从降低生产成本、稳定电解着色与封闭质量等几个重要方面考虑,应优先选用恒流控制。
- Abstract:
- The advantages and disadvantages , differences and similarities of two control methods of constant voltage and constant current anodic oxidation of aluminum were compared. The results showed that main advantage of the constant voltage control was easy operation and poor conductivity of a few workpieces had little effect to other workpieces , but a large film thickness deviation would happen when the process conditions changed greatly. The constant current control should be preferred according to several important aspects of the lower production cost , stable electrolytic coloring and sealing quality.
