Study of electroplating Zn-Sn-Ni alloy
The surface properties can be comprehensively improved by using alkaline salt pyrophosphate solution. Based on the study of the effects of bath composition, the bath composition and processing conditions were optimized for electroplating Zn-Sn-Ni ternary alloy on electrolyte copper foil, with an appropriate additive having been chosen. After the disposal, corrosion resistance, heat resistance and binding intensity of electrolyte copper foil have been obviously improved. The electrocrystalized substance obtained was composed of nano-crystals, as indicated in SEBM images. As indicated by XRD analysis on the deposit of electroplated Zn-Sn-Ni alloy, when compound additives were added, the most intensified diffraction peak was still the diffraction peak of γ-Ni5Zn21, while the diffraction peak of Zn was not obtained. This showed that Zn in the deposits existed in the form of metal compound, including δ-phase Ni3Zn22 as well as γ-Ni5Zn21. ; in pyrophosphate salt, the process of nucleation of Zn-Sn-Ni ternary alloy was similar to the process of three-dimensional successive nucleation controlled by diffuseness, as indicated by potentiostatic current transients curves.
