| 摘 要： | 通过对铝合金硬质阳极氧化过程的研究发现,在氧化膜形成的过程中氧化面产生大量气泡.气泡的出现使氧化面电流的分布状态发生改变、酸液与反应面的热传递效率降低、导电性变差,从而影响氧化膜的生长.由此提出气泡的产生会影响多孔型阳极氧化膜孔的萌生、位置分布以及孔的生长.通过建立气泡作用下氧化面孔洞形成的几何模型来探讨氧化膜孔萌生与生长.

| Abstract: | Process of hard anodic oxidation by using A1 alloy was studied. Lots of air bubble were formed on the oxidation surface in the process of forming oxide film. Distribution state of current on oxidation surface will be changed. Heat transform ratio between acid liquid and reaction surface will be decreased. Electric conductivity will be declined and the growth of anodic oxide film was affected by the emergence of air bubble. Bourgeon, location distribution and growth of porosity anodic oxide film affected by the formed air bubble were brought forward. Bourgeon and growth of oxide film hole were discussed by setting up a model about the forming of oxide film hole under the effects of air bubble. |
