Abstract
The phase composition of electrochemically obtained Ag-In alloy coatings electrodeposited at different conditions was determined. With the increase in the current density, both indium content and heterogeneity of the deposited layers increase. The amount of the indium-richer phase increase as well. Before the thermal treatment, the phases Ag, Ag3In, and In4Ag9 are observed in coatings with spatio-temporal structures. As a result of heating the new phase Ag4In appears at temperatures above 500 °C and indium is oxidized up to In2O3 from the oxygen in the heating chamber. Up to 500 °C, the spatio-temporal structures are still visible. Probably they consist of both Ag-rich α-phase and one of the phases of the alloy system with small indium content, such as Ag4In or Ag3In.
