Abstract. In this work the formation of protective coatings on VT1-0 commercially pure titanium by plasma electrolytic oxidation (PEO) and subsequent fluoropolymer treatment is presented. The structure, morphology, corrosion, and mechanical properties of the formed composite coatings were studied. It was established that PEO coatings are an excellent basis for the formation of a solid composite layer with high adhesion to its surface. The presence of polytetrafluoroethylene in the composition of the coating reduces the corrosion current density by 4 orders of magnitude and increases the wear resistance by 2 orders of magnitude in comparison with the base PEO coating.
