摘要：
The composition of films formed by plasma electrochemical oxidation-deposition on aluminum and titanium in aqueous solutions containing both Ni(II) and Fe(III) polyphosphate complexes is studied. Elementary compositions of the outer part of the layers on aluminum and titanium differ insubstantially. Concentrations of nickel and iron (up to 30 wt %) in the films vary in proportion to their molar ratio in the electrolyte. Upon annealing in air, simple and multiple metal (M) oxides and phosphates crystallize in the layers, particularly, AlPO4, NiAl2O4, and Fe2O3 on aluminum, while Ni2P2O7, Ni0.5TiOPO4; NaTi2(PO4)(3), M(II)M(III)Ti(PO4)(3), FePO4, and Fe2Fe(P2O7)(2) on titanium.
