摘要：

The relationship between galvanostatic oscillations and formation of spatio-temporal structures on the electrode surface during electrodeposition of silver-indium alloy coatings were established. The influence of the natural and forced convection onto the structure formation were investigated. A relationship between Ag to In metal ratio in the electrolyte and the current density has been established in slow-stirred electrolyte, which allows the reproducible formation and observation of the self-organization periodic structures also in stirred electrolytes. The diffusion coefficients of the reacting silver and indium species are experimentally determined. It was shown, that the formation of the spatio-temporal structures in Ag-In alloy electrodeposits follows a very complicated reaction mechanism, typical for non-linear dynamic processes.
