The work deals with electrochemical doping of coatings of metals and nonmetals. The electrodepositions of zinc-chromium and nickel-phosphorus coatings are used as examples to show that the presence of donors of the components of the plating in the inner sphere of heteroligand or heteronuclear complexes contributes to their joint recovery and formation of an alloy. The data on the structure, morphology and properties of coatings are presented. It is shown that the corrosion resistance of zinc-chromium coatings is twice higher than of those with zinc. After storage, nickel-phosphorus coatings retain their ability to low-temperature soldering.
Keywords: electrochemical doping, coating, zinc-chromium, nickel-phosphorus, heteroligand and heteronuclear complexes.
