| Description |
Pulse electrodeposition was used to produce
zinc deposits from an alkaline non-cyanide electrolyte with
additives. The influence of additives’ concentration and
pulse parameters, such as ON-time, OFF-time, and pulse
peak current density on the grain size, surface morphology,
and crystal orientation were investigated. In an additive free electrolyte, increase in OFF-time at constant ON-time
and peak current density decreases the grain size while the
latter increases with increasing ON-time at constant OFFtime
and peak current density. A progressive decrease of
grain size was observed with increasing peak current
density up to 5 Adm-2 at constant ON-time and OFF-time
in both additive-free electrolyte and bath containing additives.
Zinc with an average crystallite size of 34 nm was
obtained at 5 Adm-2 from electrolyte containing additives.
The preferred orientation of the zinc deposits obtained at
6 ms (ON-time), 51.5 ms (OFF-time) and 5 Adm-2 (peak
current density) with electrolyte containing additives was
prismatic [10.0] plane.
