Silver was electrodeposited in AgNO3 aqueous solution confined in a quasi-two-dimensional electrolytic cell. Ag(+) ion concentration profile in the electrolyte solution layer was visualized by a holographic interferometer. The measured surface concentration of Ag(+) ion decreased much slower than the expected value based on the transient diffusion model. Then, the numerical analysis was conducted in order to quantitatively analyze the ionic mass transfer rate enhanced by a kind of natural convection induced even in such a shallow electrolyte layer. The effect of electrolytic cell height on the induction of natural convection was also analyzed. Furthermore, silver nucleation phenomena onto HOPG substrate were examined. The effect of gravitational level on nucleation phenomena was quantitatively analyzed. The aim of this work is to clarify the effect of gravitational strength both on ionic mass transfer rate in the electrolyte and the metal crystallization process. Based on these data, the research to utilize different gravitational level and magnetic field to the electrochemical processing is proposed.
