| 中文摘要: |
| 在磷酸盐体系电解液中，采用恒电压方式对A231D镁合金进行微弧氧化获得陶瓷膜。通过正交试验，以陶瓷膜厚均匀性和48h腐蚀率为主要研究指标，并结合陶瓷膜层的表面质量，对磷酸盐体系电解液配方进行了研究，得到适宜的电解液配方为：15. Og/L Na5P3010.2. Og/L NaOH、1.Og/L NaW04 .2. Og/L Na2EDTA。用X射线衍射仪(XRD)分析了陶瓷氧化膜的相组成，同时采用中性盐雾腐蚀试验评价了陶瓷膜的耐蚀性。结果表明：陶瓷膜主要由Mg、Mg0和Mg2P207相组成，得到的氧化膜层具有一定的耐蚀性能。 |

| Micro-arc oxidation of A231D magnesium alloy was studied in the phosphate system electrolyte at a constantly applied permanent voltage. To optimize the formulation of phosphate system electrolyte, taking homogeneous of ceranuc coating and 48 hoursrate of corrosion combining with its apparent quantity as target, the orthogonal experiment was used in the research. The obtained feasible is as follows : 15. Og/L Na5P3010 , 2. Og/L NaOH, 1. Og/L NaW04 , 2. 0 g/L Na2EDTA. The phase compose was analyzed by X-ray diffraction ( XRD) , and the corrosion resistance of ceramic coating was measured by soak test in NaCI solution and neutral salt spray test. It is found that the coating is mainly composed of Mg, Mgo and Mg2P207, and has certain corrosion resisting property. |
