Abstract

Die vorliegende Erfindung schafft ein Schichtsystem zur Rotor-/Statordichtung einer Strömungsmaschine, insbesondere eines Verdichters, welches zwischen Bauteilen der Strömungsmaschine angeordnet ist und bei einer Relativbewegung der Bauteile zueinander derart einlauffähig ist, dass zumindest eines der Bauteile in das Schichtsystem einläuft, mit: einer auf zumindest einem der Bauteile angeordneten ersten Haftschicht; einer auf der ersten Haftschicht angeordneten Schutzschicht; einer auf der Schutzschicht angeordneten zweiten Haftschicht; und einer auf der zweiten Haftschicht angeordneten Einlaufschicht, welche weicher als die Schutzschicht ausgebildet ist. Die vorliegende Erfindung schafft ferner ein Verfahren zum Herstellen eines Schichtsystem zur Rotor-/Statordichtung einer Strömungsmaschine sowie eine Strömungsmaschine, insbesondere einen Verdichter, mit einem Stator; einem relativ zu dem Stator drehbar gelagerten Rotor; und einem derartigen Schichtsystem.

The present invention provides a layer system for rotor / stator seal of a turbomachine, in particular a compressor, which is arranged between components of the turbomachine and in a relative movement of the components to each other is einlauffähig that at least one of the components enters the layer system, with: a on at least one of the components arranged first adhesive layer; a protective layer disposed on the first adhesive layer; a second adhesive layer disposed on the protective layer; and an inlet layer disposed on the second adhesive layer, which is softer than the protective layer. The present invention further provides a method for producing a layer system for rotor / stator seal of a turbomachine and a turbomachine, in particular a compressor, with a stator; a rotor rotatably mounted relative to the stator; and such a layer system.
