Abstract
The paper presents a method of the formation of the composite polymer-containing coatings on a MA8 magnesium alloy by plasma electrolytic oxidation (PEO) with the subsequent application of a polymer component by spray-coating with suspension of superdispersed polytetrafluoroethylene. Composite layers significantly increase the corrosive properties of magnesium alloy. A decrease of the corrosion current density more than 3 orders of magnitude in comparison with the base PEO-coating is observed. Formed polymer-containing layers have hydrophobic properties: the values of the contact angle attain to 152°.These coatings significantly expand the field of application of magnesium alloys in such industries as automotive, aviation, instrument engineering and implantation surgery.
