Abstract
The process of the electrochemical deposition of an iron-tungsten alloy is investigated. It is established that, though the solution is prepared on the basis of compounds of Fe(II), stable deposition of dense deposits of the alloy begins only after a larger fraction of these compounds converts into compounds of Fe(III) as a result of oxidation by oxygen of air and anodic oxidation. The parallel evolution of hydrogen is accompanied by the process of incomplete reduction of iron ions. The current efficiency for the alloy in the working conditions exceeds 50%. The content of tungsten in the obtained alloys is weakly dependent on the current density and amounts to nearly 45% (by weight).
