本文对铝电镀之前的各种典型的阳极氧化预处理进行了评论.重点放在讨论技术革新的论文上.看来,磷酸阳极氧化的论文最多,然而,有许多别的方法也获得了工业应用.与通常使用的浸渍预处理相比,氧极氧化预处理有许多优点,主要的是:不需要氰化处理;对阳极氧化前的清洗要求不严以及化学药品成本低.但是,镀层在阳极氧化膜上的附着力对合金成分极为敏感,同时,阳极氧化需要消耗大量的能源.因此,为了在工业上获得更广泛的应用,对这种技术还需作进一步的研究.
This article reviews various typical anodizing pretreatments prior to aluminum electroplating, with an emphasis on papers discussing technological innovations. It appears that the largest number of anodes for phosphoric acid anodization appears, however, and many other approaches are also available for industrial applications In contrast to commonly used impregnation pretreatments, oxygenate pretreatment has many advantages, notably the absence of cyanidation, the lack of stringency of pre-anodic cleaning and the low cost of chemicals, Adhesion on the oxide film is extremely sensitive to the composition of the alloy, and at the same time, anodizing consumes a large amount of energy, so more research is needed on this technology for wider industrial application.
