Abstract:The process of electroplating Sn-Zn alloy which has good properties and can be used to replace Cd electroplating layer, was researched, the results showed that Sn-Zn alloy, which is bright and fine and has high corrosion resistance and low hydrogen embrittlement as well, can be obtained from citrate-tarate mixed system. The mechanism of additives was also studied by rotating disk electrode, cycling voltammetric stripping and polargraphy methods, the result showed that the levelling mechanism of additive A accords with diffusion mechanism proposed by Kardos O.
Key words: Sn-Zn Alloy electroplating additive
