Abstract—Oxide–phosphate layers 20 to 150 m thick were obtained on titanium by plasma electrolytic dep-
osition in individual and mixed aqueous electrolytes with polyphosphate complexes of zirconium(IV), bar-
ium(II), and copper(II). Formation features, thickness, elemental and phase compositions, and surface morphol-
ogy of the films are presented. Depending on the electrolyte composition, synthesis conditions, and temperature
of annealing in air, some simple and double phosphates of titanium and zirconium are formed, including
ZrP2O7, NaTi2(PO4)3, BaTi2(P2O7)2, Zr0.2Ti0.8P2O7, and CuTi2(PO4)3.
