Zusammenfassung:Disclosed is a method for the plasma-electrolytic deposition of a titanium-based non-metallic protective coating on an aluminum-containing material that exhibits excellent resistance to corrosion and high resistance against wear; a coated aluminum-containing metallic article, wherein the coating comprised of oxides and hydroxides of the elements titanium and aluminum has a thickness of at least 15 microns and a cross-section hardness (HV) of at least 800; and a device comprising an arrangement of two adjacent parts at least one being selected from an aluminum-containing metallic material that is coated according to the method and in frictional connection with the other part wherein under operation the frictionally connected parts move relatively to each other, such as, pistons moving in the cylinder within the powertrain of a vehicle.
