摘要: 应用X-射线衍射、红外光谱、热重和差热分析对铝在硫酸中阳极氧化后经BY02封孔剂冷封孔处理的氧化膜组成结构进行了研究,结果表明:铝的阳极氧化膜主要由无定形氧化铝组成,膜中含有SO_4~(2-);在冷封孔反应过程中形成了AlOOH、Ni(OH)_2和AlF_3等产物。文中还讨论了冷封孔反应机理。

Abstract：The composition and structure of anodic oxide films on aluminum formed in sulphuric acid solution and cold sealed with BY02 agent were investigated by means of X-ray diffraction, infrared spectroscopy, thermogravimetry and differential thermal analysis. Anodic oxide films are mainly composed of amorphous alumina, including sulphate, Boehmite AlOOH, nickel hydroxide Ni(OH)_2 and aluminum fluoride AlF_3 are formed in cold sealing. The cold sealing reaction mechanism was also discussed.
