Coatingsystem for the rotor/stator sealing of a turbo machine

The adherent layer (20) is metallic. The first and second layers (16, 18) of the running-in coating (12) are ceramic. They are not graduated, i.e. they have the same consistency over their thickness. Adherent layer (20), first and second layers are coated directly onto each other, i.e. without inter...

Zusammenfassung:	The adherent layer (20) is metallic. The first and second layers (16, 18) of the running-in coating (12) are ceramic. They are not graduated, i.e. they have the same consistency over their thickness. Adherent layer (20), first and second layers are coated directly onto each other, i.e. without intermediate layers.
