| 中文摘要: |
| 在铝酸盐体系中对AZ91D镁合金进行微弧氧化处理。利用田口式实验设计法探讨微弧氧化过程电参数对膜层耐蚀性的影响,确定了最佳工艺参数为:电压180V,氧化时间30min,频率50Hz,占空比30%。用交流阻抗分析膜层的耐腐蚀性能,结果表明:最佳工艺条件下所制备微弧氧化,膜层电阻比镁合金基体提高了2个数量级,耐蚀性有所增强。 |
| 英文摘要: |
| Micro-arc oxidation films were prepared on magnesium alloy AZ91D in a aluminate electrolyte. The effects of electric parameters during the micro-arc oxidation process on properties of MAO films were systematically investigated using the Taguchi experimental analysis method. The optimized parameters are 180 V voltage, 30 min oxidation time,50 Hz frequency,30% duty cycle. The corrosion resistance of the MAO film was examined by means of AC impedance.The results show that the resistance of MAO film treated on optimized conditions increase by two orders compared with the magnesium alloy substrate. This enhances the corrosion resistance of the magnesium alloy. |
