Title
(DE) Verfahren zur Herstellung korrosionsschützender anorganischer Überzüge auf leitfähigen Werkstoffen auf der Basis von nanoskaligen Partikeln
Abstract
(DE)

Metalloberflächen müssen unter agressiven Bedingungen gegen Korrosion geschützt werden. Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung korrosionsschützender anorganischer Überzüge auf elektrisch leitfähigen Werkstoffen mittels elektrostatischer Abscheidung nanoskaliger Partikel. Dem Abscheiden der Partikel durch elektrostatische Abscheidung folgt hierbei eine thermische Nachbehandlung, die in einer geschlossenen Schicht resultiert.
