Analysis of Effect of Concentration Dependence of Exchange Current on Metal Electrodeposition into Template Nanopores

Abstract: The metal electrodeposition into the nanopores of template of porous anodic alumina type under the conditions of mixed kinetics of metal deposition is studied theoretically using analytical and numerical methods. Two main periods of the process are studied: the non-steady-state formation of diffusion layer in the template pores and much longer process of pore filling with the metal. The effect of nonlinearity of the concentration dependence of the exchange current density of metal electrodeposition on the variation of the current density with the time during the diffusion layer formation and pore filling with the metal is studied.
