Abstract
In this paper, requirements for wear-resistant coatings of Ni–40%W manufactured by electrochemical deposition are determined, and the electrolyte stability is studied. The influence of temperature and current density on the deposition of the Ni–W alloy from a citrate electrolyte was researched, and the optimal deposition mode was found. The maximum operating time of the electrolyte is established by the dependence of the current efficiency for the Ni–W alloy on the electric power transmission. The necessity of using membrane electrolyzers during the deposition of nickel-tungsten coatings is substantiated.
