FIELD: technological processes.
SUBSTANCE: invention relates to production of ceramic coatings by electroplasma sputtering on articles from titanium alloys and can be used in instrument-making and machine building, in particular, in parts of compressors and turbines of gas-turbine engines, implanted medical structures. Method of forming a ceramic coating based on zirconium dioxide on an article from a titanium alloy includes electroplasma sputtering a dioxide-based coating and its modification by micro-arc oxidation in an aqueous alkaline electrolyte based on sodium hydroxide with the concentration of 1–3 g/l in the anode mode at the constant current density of (2–2.5)×103 A/m2 for 20–30 minutes.
EFFECT: technical result is improved adhesion and microhardness of the coating based on zirconium dioxide.
