A novel electrolyte based on CuSO4 complexed by K4P2O7 and AgNO3 complexed by KI is studied for the deposition of CuAg alloys having a range of Ag compositions between 3 %at. and 16 %at. The deposition occurred in non stirred conditions at 50°C. A characterization of the coatings is presented with a focus on the properties of the supersaturated alloy and the demonstration of its metastable behavior. The electrochemical characterization of the solution is also reported.

Abstract

A novel electrolyte based on CuSO4 complexed by K4P2O7 and AgNO3 complexed by KI is studied for the deposition of CuAg alloys having a range of Ag compositions between 3 %at. and 16 %at. The deposition occurred in non stirred conditions at 50°C. A characterization of the coatings is presented with a focus on the properties of the supersaturated alloy and the demonstration of its metastable behavior. The electrochemical characterization of the solution is also reported.
