Influence of additives of oxyacids and complexes, containing acetate, semi- and tiosemicarbaziddiacetats fragments on process of electro sedimentation of iron is considered. Increase of stability of electrolytes of iron and improvements of corrosion properties of the iron coverings received from electrolytes of iron in the presence of organic additives is established. The influence of additives on the process of electro sedimentation of iron coverings is explained by adsorption of complexes of iron (II) and iron (III) with ligands in a superficial layer. Formation of adsorbed complexes can result either in acceleration or deceleration of discharge of ions of iron in dependence on the nature of organic additives.
