Popis:	The mechanism of the indium electrodeposition process from aqueous solutions on bismuth cathodes has been investigated as well as the evolution with time of the composition of the deposits after electrodeposition. The potentiometric results and the changes in composition and structure are explained by considering the transport phenomena and the reactions occurring in the solid state owing to indium diffusion into the electrode and to the formation, generally, of the multiphase layer InIn 2 BiIn 5 Bi 3 InBi. Such analysis allows estimation of the room temperature average diffusion coefficient of indium in the three intermetallic compounds (ca. 10 −15 −10 −16 m 2 s −1 ). Moreover, consideration of the indium chemical potentials within each compound makes it possible to account for the evolution of the system with time to InBi.
