Abstract — The electrolyte and parameters of high-voltage anodic–cathodic process, which enable one to apply rather thick (to 340 µm) oxide coatings to titanium alloys, are selected. Characteristics of the coating formation on aluminum and titanium alloys are compared. It is found that, on the titanium alloys, the stage of microarc discharges occurs only at relatively high anodic and cathodic components of the current density. The voltage chronograms and oscillograms also have pronounced specific features.
