据英刊《表面处理》1985年第3期报道,为使铝及铝合金表面光亮,采用了混合酸的溶液来代替阳极氧化处理液,该溶液的浓度(重量％)是磷酸-80、硫酸-15、硝酸-15。还要往该溶液中加入少量的铜和溴离子添加剂作为防腐剂。为了降低电解液的价格,可用硫酸代替部分磷酸。但是,在这种情况下,可 According to the British journal “Surface Treatment” 1985 the third period reported that in order to make aluminum and aluminum alloy surface bright, mixed acid solution instead of the anodizing solution, the solution concentration (wt%) is phosphoric acid -80, sulfuric acid -15, nitric acid -15. Also add a small amount of copper and bromide ions to the solution as a preservative. In order to reduce the price of electrolyte, sulfuric acid can be used to replace part of the phosphoric acid. However, in this case, yes
