Electrodeposition of rhenium and its alloys

Resumo

The processes of electrodeposition of rhenium and its alloys with nickel from aqueous solutions are considered. The results of theoretical and experimental studies of the process of perrhenate ion reduction are analyzed: the data on the possible mechanisms of the cathodic process, participation of atomic hydrogen in it, potentials of transition of rhenium to different oxidation degrees. Codeposition of rhenium and nickel is discussed. The effect of complexation on the current efficiency of rhenium deposition is considered. Information of the sources of data discussed in this paper is provided.
