Das Verfahren beruht darauf, dass die Oberflaeche zunaechst chemisch und/oder physikalisch aktiviert und dann mittels eines Sols beschichtet wird.EP 1277851 A UPAB: 20030307 NOVELTY - Coating passivated metallized surfaces of components comprises chemically activating the surfaces using a tenside-containing solution or by reducing using a reducing agent or direct voltage or by physically activating the surfaces by sputtering; and coating the activated surfaces with a sol and forming a gel. DETAILED DESCRIPTION - Preferred Features: The surfaces energy is increased to more than 40, preferably more than 50 mN/m after being activated. During chemical activation, a direct voltage is applied to the component. During physical activated, the sputtering is carried out in a hydrogen-nitrogen-argon atmosphere. The coated surface is made from smooth or structured chromium, steel, nickel and/or aluminum. USE - Used for coating the surfaces of sanitary and kitchen fittings. ADVANTAGE - The coating effectively avoids the adhesion of dirt.de608670patent2001-10134473
