| 中文摘要: |
| 为了研究阳极氧化工艺条件对硬质氧化膜的厚度、耐蚀性、表面形貌的影响。利用正交试验优化了铝合金硬质阳极氧化的工艺条件，采用扫描电镜( SEM)观察了硬质阳极氧化膜的表观形貌，并探讨了槽液温度和硫酸浓度对氧化膜耐腐蚀性的影响。结果表明：有利于硬质阳极氧化膜厚度增加的最佳工艺条件为：硫酸浓度150g/L，电流密度3.5A/dmz，氧化时间180min，槽液温度-5 -OOC；SEM照片表明：硫酸浓度增加，氧化膜的孔径增大，孔隙率增加。 |
| 英文摘要: |
| The effects of anodic oxidation process on thickness, corrosion resistance and surface morphology of hard oxidation film were studied. Aluminum alloy hard anodizing process was optimized with orthogonal experiments. The surface morphologies of anodic oxidation film were studied by SEM. The effects of anodizing temperature and sulfuric acid concentration on corrosion resisting were tested. The results show that the optimized process which is in favor of increasing hard anodic oxidation film thickness is as follows : sulfuric acid concentration of 150g/L, current density of 3. SA/ dm2 , anodizing time of 180min, anodizing temperature of - 5 ~O℃ . The SEM photographs show that the aperture and the hole ratio of films will enlarge with the increasement of the sulfuric acid concentration. |
