摘要：

Is it possible to obtain periodic spatio-temporal structures during electrodeposition of Ag-Sb and Ag-Sn alloys from non-cyanide electrolytes? To find out suitable electrolytes for the deposition of the antimony-tin alloy in order to obtain coatings in a wide range of compositions as well as the conditions for obtaining of heterogeneous coatings - these are the questions to be answered in the present study. It was established, that spiral structures formed by different alloy phases are observed during electrodeposition of silver-tin alloys from thiocyanate-pyrophospate electrolytes. The phase analysis shows that the structures are formed by the phases Ag3Sn and Sn. Depending on the electrolysis conditions during deposition of Ag-Sb alloys it is possible to obtain structures with different level of spatio-temporal organization from thiocyanate electrolyte. The pyrophosphate-tartrate electrolytes for the deposition of Sb-Sn alloys is developed for deposition of alloy coatings appropriate for investigation of their phase heterogeneity and properties.
