Paper Title:
Study of Electroplating Zn-Sn-Ni Alloy
  Abstract

When Zn-Sn-Ni ternary alloy is electroplated on electrolyte copper foil, the surface properties can be comprehensively improved by using alkaline salt pyrophosphate solution. After the bath composition and processing conditions are optimized, and an appropriate additive is chosen, the SEM images shows the electrocrystalized substance obtained is composed of nano-crystals. Besides, XRD analysis on the deposits of electroplated Zn-Sn-Ni alloy shows Zn in the deposits exist in the form of metal compound, including δ phase Ni3Zn22 as well as γ Ni5Zn21. This indicates under the pyrophosphate salt the process of nucleation of Zn-Sn-Ni ternary alloy is similar to the process of three-dimensional successive nucleation controlled by diffuseness. All these demonstrate that after the disposal of this study, the corrosion resistance, the heat resistance and the binding intensity of electrolyte copper foil are obviously improved.
