| Abstract: |
| The electrodeposition behavior, structure and morphology of zinc from ZnSO4-(NH4)2SO4 baths have been investigated by cyclic voltammetry, potentiodynamic polarization techniques, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that the initial deposition potential moves positively by adding ChCl, the zinc electrodeposits with the preferred orientation of (101) and (100) are composed of large and thick zinc flakes. However, the initial deposition potential moves negatively by adding BH, the zinc electrodeposits with the preferred orientation of (101) are composed of stacked layer of thin zinc flakes. |
