Abstract—The process of deposition of the Re–Ni alloy, its current efficiency, and the alloy composition are
studied as a function of the current density and the solution temperature. The hydrogen content in the deposits,
their surface morphology, internal structure, and properties as the cathodic material for HER are examined. It
is assumed that besides the high rhenium content, the high catalytic activity of nickel–rhenium alloys is asso-
ciated with the high degree of their structural disordering.

Keywords: electrodeposition, alloys, nickel–rhenium, structure, hydrogen in metals, electrocatalysis
