Iron–tungsten alloys were obtained from citrate electrolytes. A relation between Fe(II) and Fe(III), which permits to maintain stability of electrolyte as well as to obtain high quality deposits for a long time. Results of the investigations show that discharge of iron ions takes place from the three valent ions. It was found that the concentration of sodium wolframate in the electrolyte contributes to the codeposition of tung-sten, increasing its ratio in the alloy. It is established that current efficiency and composition of iron–tungsten coatings depend on current density and conditions of electrolysis. Microhardness of iron–tungsten deposits increase with the increase of temperature of deposition and depends on the content of tungsten in the alloy. Investigations with electron microscope has shown that on the surface of alloy superficial non homogeneous films with the content of tungsten and oxygen different from that in the deposition are formed. Obtained al-loys have concentration and structure inhomogeneities.
