Abstract (en)
[origin: WO2018197114A1] The invention relates to a ceramic sealing system between a rotor blade (120) and a housing (1''). By means of the combination of a small porous zirconium oxide layer (11) on a turbine rotor blade, which zirconium oxide layer faces a ceramic layer system (15', 15'') of higher porosity, durable sealing systems are achieved. The housing (1'') has a metal substrate (7), a metal adhesion-promoting layer (10), and a thick, outer, ceramic layer (15', 15'') based on zirconium oxide, in particular having a porosity ≥ 14%.
