Galvanic nanostructured coatings with Fe-Ni, Co-Mn, Ni-Cr alloys with enhanced operational properties are obtained. Three mechanisms of ultrafine particles formation are considered: usage of the high-voltage alternating current (HVAC) method (Fe-Ni, Co-Mn), presence of a new hexagonal phase ε-Fe, which has dimensional effects. 2) introduction of a special carbamide additive, N-acid (Ni-Cr). 3) due to multilayer films Cr(OH) 3 ·(H 2 O)·2H 2 O in the absence of an inhibitor (Ni-Cr alloy), the relationship between the nanostructure forming mechanism and the spectrum of functional properties is shown.
