METHOD FOR OBTAINING NANOCOMPOSITE COATINGS

摘要

FIELD: metallurgy.SUBSTANCE: method involves microarc oxidation of surface of products from titanium alloys in alkaline electrolyte with solid-phase ingredients in the form of powders; at that, nanopowders of titanium oxide with size of less than 0.05 mcm are used, and final coating is formed at cathodic treatment in acid electrolyte at temperature of 450°C by deposition of metallic phase inside pores of oxide coating.EFFECT: improvement of microhardness of coatings and corrosion resistance of products due to reduction of porosity is provided.1 tbl, 1 ex
