How the proportional increasing of components' concentration of aqueous electrolyte and the transition from anodic to alternating–current anode–cathode polarization influence energy inputs to oxide structures generation and their characteristics has been investigated. It is shown that, in the case of PBW method, this approach results in a decreasing of approximately three times the energy input without any sufficient variation of elemental and phase composition of the covers, their thickness, corrosion resistance, wetting by aqua and oils, or porosity.
