Abstract

Die Erfindung betrifft eine Verschleißschutzschicht für ein reibend beanspruchtes Bauteil, umfassend eine Hartchromschicht. Auf die Hartchromschicht ist eine Schicht aus einem Polysiloxan aufgebracht. Weiterhin betrifft die Erfindung ein Verfahren zum Auftragen der Verschleißschutzschicht. Hierzu wird das Bauteil zunächst mit einer Hartchromschicht beschichtet. Abschließend wird auf die Hartchromschicht eine Polysiloxanschicht aufgebracht.

The invention relates to a wear protection layer for a frictionally stressed component, comprising a hard chrome layer. On the hard chrome layer, a layer of a polysiloxane is applied. Furthermore, the invention relates to a method for applying the wear protection layer. For this purpose, the component is first coated with a hard chrome layer. Finally, a polysiloxane layer is applied to the hard chrome layer.
