Abstract

The process of electrodeposition of Ni-Mo-V alloys from an alkaline tartrate bath was studied. The effect of the cathodic current density on the chemical composition, phase composition and surface morphology of Ni-Mo-V alloy deposits, as well as on the current efficiency of the deposition process, was determined. Codeposition of molybdenum and vanadium with nickel and formation of the Ni-Mo-V alloy is possible due to the effects of depolarization and overpolarization occurring in the process of codischarge of the complex ions of these metals. It was observed that the use of cathodes electrodeposited with Ni-Mo-V alloy containing 9–12% Mo and 0.1–0.2% V for water electrolysis resulted in a decreased overpotential for hydrogen evolution.
