Abstract
Zinc was electrodeposited at temperature from 20$^{\circ}C$ to 60$^{\circ}C$ over the ranges of the current density from 2 to 20 A/dm2 in acid chloride bath. The cathode overpotentials increased with increasing current density and decreasing tem-perature. The (10$.$3)-(10$.$2) preferred orientation developed at cathode overpotentials below about 450mV, the (10$.$3)(10$.$2)-(10$.$1) texture developed at overpotentials between 500mV and 950mV, and the (00$.$1) (10$.$3) texture developed at cathode overpotentials about 1000mV. The (00$.$1) (10$.$3) preferred orientation was also formed at the lower potentials between 400mV and 850mV at temperatures above 40$^{\circ}C$. The preferred orientations of the zinc deposits was discussed was discussed with both cathode overpo-tential and surface energy of deposit lattice planes. The pyramid type of structure with macrostep developed at low cathode overpotentials and the truncated pyramidal type developed at higher overpotenial.
