【 摘 要 】

Non-cyanide electrolytes for silver-indium alloys deposition investigated in order to adjust electrolysis conditions thus to observe the formation of spatio-temporal structures onto the electrode surface. It was established that the electrolytes for silver-indium deposition prepared with the excess of thiocyanate and iodide complexing agents are stable in time. The alloy electrodeposition is of a regular type where the silver is the more positive metal. The observed oscillations of the potential during galvanostatic deposition of indium in the thiocyanate solution are suggested to appears due to the formation/destruction of some passive layers on the electrode surface. Spatio-temporal structures could be observed during electrodeposition of the alloy from thiocyanate electrolytes.
