Abstract

The influence of pulse electrodeposition parameters (i.e., current-on time, current-off time and peak current density) on the grain size and orientation of zinc deposits was investigated in acidic sulfate electrolyte. The scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses indicate that the pulse parameters play an important role in the grain refinement of nanocrystalline zinc coatings. As varying peak current density (1-2 A/cm 2), current-on time (1-6 ms) and current-off time (4-18 ms), nanocrystalline zinc coatings are produced in the grain range 60 to 35 nm. The pulse parameters have a slight influence on the orientation of nanocrystalline zinc coatings.
