Abstract
(DE)

Metalloberflächen müssen unter agressiven Bedingungen gegen Korrosion geschützt werden. Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung korrosionsschützender Überzüge auf metallischen Werkstoffen unter Verwendung nanoteiliger Pulver von Metallen oder Oxiden. Die Schichtaufbringung erfolgt in einem mehrstufigen Verfahren, welches das thermische Aufsintern der Nanopulver als zentralen Schritt beinhaltet bzw. eine derartig hergestellte Schutzschicht.

(EN)

Production of corrosion resistant coatings for metals comprises applying metallic or non-metallic inorganic nano-particulate powder in an organic matrix onto the metal surface, removing the organic matrix at 300-600 deg C, and sintering the nano-powder at 300-900 deg C to form a layer. An Independent claim is also included for the corrosion resistant coating produced. Preferred Features: The metal surface is degreased before applying the suspension. The organic matrix is made of paraffin or other high molecular material.
