Crystal Orientation and Surface Morphology of Sono-Electroplated Zinc Film from Alkali Zincate Bath

Abstract:

Zn plated on Cu plate from 0.65 mol/dm3 alkali zincate solution in 8 mol/dm3 KOH bath Electrolysis was carried out as current density of 10 - 100 mA/cm2. The sonication was prepared 40 kHz. The current efficiency was 76.1 % at 10 mA/cm2 in 0.10 mol/dm3 zincate and 100 % in 0.15 mol/dm3 zincate at 50 mA/cm2. The current efficiency and thickness of diffusion layer affected with the agitation of micro-jet. Surface of film was smooth and dense as particle crushed down with the shockwave pressure. (112) plane moved horizontally to <113> direction under the compressive stress or shearing stress.

[14] JCPDS 4 - 0831 Summary The current efficiency and thickness of diffusion layer affected with agitation of micro-jet. The surface was smooth, dense and homogeneity. Or, when the shock wave pressure was applied on the particle that deposited on surface, the particle was crushed, and was compressed with adjoining particle. Finally, it consisted like one particle. Surface was smooth and dense as particle crushed down with the shockwave pressure. (112) plane moved horizontally to <113> direction under the compressive stress or shearing stress.
