Currently, the method of microarc oxidation (MAO) is widely used due to its ability to synthesize on the surface of valve metals and alloys ceramic layers used for various purposes [1]. Thus, in [2, 3] the possibility of the incorporation of nickel (nickel oxide) in MAO coatings formed on titanium alloys in nickel-containing acidic and alkaline electrolytes has been explored with a view to designing so called ―partially soluble anodes‖. They are used in installations for the production of hypochlorites, chlorates and perchlorates, and can also be used in water treatment, electroplating and other areas of electrochemical production. However, they are having a limited service life due to corrosion damage. For making of low soluble titanium anodes, the formation on their surfaces of MAO coatings with a high content of transition metal oxides (with a relatively high electrical conductivity) that provide small anodic dissolution currents and low electrical insulation characteristics is requires.  In this work the effect of additives of nickel, cobalt or iron sulfate in a silicate-alkaline electrolyte for MAO on the elemental composition, electrochemical behavior and electrophysical characteristics of coatings formed on titanium was investigated. It was established that these additives are incorporated into the oxide layer. Increase in the content of these components in the electrolyte leads to a decrease in their content (as well as silicon) in the coatings and increase in the content of titanium. Electrochemical studies have shown that the minimum anodic dissolution currents at low electrical strength are characteristic for samples treated in electrolytes containing 1 g/L NiSO4. The table presents data on the thickness (h), breakdown voltage (U) and electrical strength (E) at direct and alternating currents of MDO coatings obtained in various electrolytes. It can be seen that in silicate-alkaline electrolyte with addition of 3 g/L FeSO4 MAO coatings are formed with lowest electrical insulation characteristics required for partially soluble titanium anodes.
