A formation of protective composite coatings based on nickel and organic substance of inert nature, containing a corrosion inhibitor, encapsulated in a polymer shell, was studied. The microcapsules weresynthesized in an aqueous-organic emulsion using the method of formation of shell of the modified gelatineon the surface of microdroplets. Composite coatings were obtained by electrochemical codeposition of nickelmatrix and microcapsules, suspended in the electrolyte. Changes of surface morphology, microhardnessand corrosive properties of coatings with respect to changes of deposition parameters of coatings wereinvestigated. The distribution of particle sizes in coatings depending on the current density was studied. It was shown that an increase in the mass fraction of the microcapsules in the coating leads to an increase in its corrosion resistance.
