在硫酸溶液中加入各种有机酸,以抑制氧化膜的溶解,使其能在常温下进行氧化,已有过很多研究,采用乳酸、甘油的常温阳极化就属这种。为了了解这种电解液对各种铝合金的适用情况,我们对 LD5、LC4、LY11、LY12、LF2、LF21、L4等七种变形铝合金和 ZL13、ZL11等两种铸铝合金进行试验,并对一些零件投入了小批生产,取得了较好的效果。 In the sulfuric acid solution by adding a variety of organic acids to inhibit the dissolution of the oxide film, so that it can be oxidized at room temperature, there have been many studies using lactic acid, glycerol at room temperature anodizing it. In order to understand this electrolyte for a variety of aluminum alloy application, we have LD5, LC4, LY11, LY12, LF2, LF21, L4 and other seven kinds of deformation of aluminum and ZL13, ZL11 and other two kinds of cast aluminum alloys were tested and Some small parts put into small batch production, and achieved good results.
