Abstrakt: Abstract: Cyclic voltammetry is used to study the cathode reduction of yttrium ions on a copper electrode in an YCl3-containing NaCl-KCl melt at 1023 K. The potentials of formation of copper-yttrium compounds are determined. Samples of Cu6Y, Cu4Y, Cu2Y, and CuY alloy coatings are prepared by controlled potential electrolysis; samples of Cu6Y and Cu4Y alloy coatings are prepared by no-current diffusion saturation at 973 and 1023 K. It was found that the samples prepared by no-current diffusion saturation are thicker than those prepared by electrolysis. However, the controlled potential electrolysis allowed us to prepare coatings of a given composition. [ABSTRACT FROM AUTHOR]
