FIELD: processes for forming of wear-resistant, dielectric, corrosion-free and ornamental coatings on articles manufactured from aluminum, magnesium and titanium alloys. ^ SUBSTANCE: method involves using article as working electrode; submerging electrode into bath filled with electrolyte, said bath constituting main counter electrode having larger surface than article; placing additional counter electrodes and connecting them to main counter electrode; partly screening article surface by means of dielectric material, to do that, setting screens and applying dielectric material onto part of article and onto counter electrodes; applying coating onto part of article surface having area S, dm2, ranging between N/2 and N/8, where N is value of consumed electric power, kW. Article and screens with counter electrodes are to be moved relative to one another. ^ EFFECT: provision for obtaining of uniform coating having desired thickness and properties on surface of article having complicated shape and any size, increased efficiency and provision for utilization of low-power source. ^ 1 dwg, 1 ex
