Abstract
A layer system for the rotor/stator seal of a turbomachine, in particular of a gas turbine, is applied to a metallic component and can be run in with respect to a further component which can move relative to the metallic component, which, in order to improve the service life and run-in properties, is characterized by a bonding layer which is applied to the metallic component and a run-in coating which is applied to the bonding layer and comprises at least two layers, the first layer, which adjoins the bonding layer, being harder than the second layer, and the second layer having run-in properties.
