摘　　要：介绍了利用微弧氧化的方法在铝合金基体上制备有色陶瓷层的工艺研究,通过微弧实验得到制备黑褐色及深黑色膜的最佳工艺。分析了电解液的成分以及添加剂的质量浓度对氧化膜着色的影响,并讨论了实验过程中可能出现的问题及解决办法。The method that makes use of micro-arc oxidation to produce colored ceramic coating on LY12 aluminium alloy was introduced. And through micro-arc experiment, some components with dark brown and deep black ceramic coatings were obtained. The influences of the electrolyte composition, bath concentration and additives on the ceramic coating were analysed. Some possible problems appeared in the experiment and the relative measures that could be used were discussed.
