Abstract

Surface modification of magnesium alloys by plasma electrolytic oxidation (PEO) and subsequent treatment with suspension of superdispersed polytetrafluoroethylene and tetrafluoroethylene telomeric solution are presented. Electrochemical, mechanical properties and wettability of obtained composite coatings were investigated. The polymer-containing coatings decrease the corrosion current and wear by orders of magnitude as compared to unprotected magnesium alloy and base PEO-coatings.
