摘要
对KOH、Na3PO4、Na3AlF6溶液中AZ91D镁合金的微弧氧化进行了研究 ,结果表明 :该镀液最佳溶液浓度为 70g L、2 0g L、3 0g L ,能形成较好的微弧氧化膜 ,而且离子含量稳定 ,pH值基本不变 ,分散能力好 ,所得膜层厚度均匀 ,主要由MgO和MgAl2 O4组成 ,还有少量的Al2
In this paper, micro-arc oxidation Study on AZ91D magnesium alloy in the electrolyte contained KOH,Na 3PO 4 and Na 3AlF 6 was investigated. The results showed that the electrolyte could form a nice micro-arc oxidation coating of uniform thickness , with stable ion content, unchangeable pH value and nice dispersion. With cubic structure and Mg. The coating was mainly composed of MgAl 2O 4, MgO and a little Al 2Mg 3.
