The use of the separated anode and cathode spaces during electrodeposition of the Fe–W alloy from a citrate bath (separation was carried out using a membrane with an average pore diameter of 0.74 μm) made it possible to significantly (up to 2 times) increase the current efficiency and deposition rate when using a graphite anode and to increase the performance electrolyte (constancy of surface composition and surface microhardness up to 4 A h l–1). The dynamics of changes in the concentrations of the alloy-forming components of the electrolyte was studied and it was shown that it is defined not only by the electrodeposition of iron and tungsten into the alloy, but also by the absorption of tungstate by the anode.
