<p>An abradable seal system for a gas turbine comprises a rotor blade tip (7) with an abrasive coating system (9, 11) and a stationary heat shield ring (1) facing opposite to the blade tip (7) and coated with an abradable coating. The abrasive coating system comprises an oxidation resistant and/or corrosion resistant bond coat (9) and a thermal barrier coating (11) atop of the bond coat (9). The thermal barrier coating (11) is a ZrO2 coating that is partially stabilized by Y2O3 and free of vertical macrocracks.</p> |
