A review of developments in the electrodeposition of tincopper
During the electroplating of tin, metal deposition initiated at approximately − 044 V vs Ag/AgCl and reached a limiting current density at approximately 28 mA cm − 2 (Plateau 1 in Fig 7) At more negative potentials, the current density decreased to 56 mA cm − 2 before reaching a plateau at approximately − 075 V vs 4 Conclusions It could be shown that SnZn alloys, electroplated from a neutral bath, consist of Sn and Zn phases, which are finely mixed together By use of EQCM, we can estimate the electroplating current efficiency and the corrosion current density, which are 71% and 71 μA/cm 2 (458 μA/in 2 ), respectivelyTinZinc Alloy Electroplating and Its Corrosion Behavior
