The microstructure of the zinc electrodeposits was investigated by changing the flow rate of electrolyte in zinc sulfate Bath. The cathode current efficiency increased with increasing flow rate of electrolyte. The preferred orientation of zinc electrodeposit changed from (11.2) texture to (10.3) or (10.1)+(10.2) texture with increasing current density in the range of flow rate, 0.2-1.2m/sec. The morphology of the deposits changed from the sponge deposit to the blocks of hexagonal crystallites packed together through the structures of find polycrystallite with increasing current density. The microstructure of the cross-section of the above deposits are granular structure and columnar structure respectively. The surface roughness of zinc electrodeposits decreased with increasing current density and flow rate of electrolyte.
