微孔阳极氧化铝膜的制备及膜的耐蚀性研究

Preparation and Anticorrosion Ability Study of Anodizing Aluminum Separated Membrane

研究了经硫酸溶液和硫酸加醋酸溶液氧化，并经逆向电解法剥离后的氧化铝多孔膜的耐蚀性。实验结果表明：所剥离的膜在中性介质中非常稳定，ｐＨ值小于２，膜有微量溶解。ｐＨ值大于１２时，膜的溶解性迅速增大，因此膜在此环境下不宜使用。另外。

Anticorrosion ability of anodizing aluminium separated menbrane have been studied in corrosion media. The result shows that menbrane is steady in neutral media. But the membrane is not fit to use when pH>12.
