电镀阳极按其溶解性能可分为可溶性阳极与不溶性阳极。不溶性阳极只是起导电作用和控制电流在阴极表面的分布 ,不参与金属的溶解。如镀铬中的铅锑合金阳极板、碱性锌酸盐镀锌中的镍板、氰化镀铜中的钢板等 ;可溶性阳极除具有不溶性阳极的作用外 ,还可补充主盐金属离子 ,保证其 Anodized according to their solubility can be divided into soluble anode and insoluble anode. Insoluble anode only plays the role of conduction and control current distribution in the cathode surface, does not participate in the dissolution of the metal. Such as chrome-plated lead-antimony alloy anode plate, alkaline zincate zinc-plated nickel plate, cyanide copper plating in the plate; soluble anode in addition to an insoluble anode role, but also can be added to the main salt metal ions, to ensure its
