Abstract
A component such as a turbine blade (1) of a gas turbine is provided with an intermetallic felt (2). By providing the tip (11) of the turbine blade (1) with the intermetallic felt (2) and optionally a coating of a ceramic material (3), improved protection against thermal and mechanical effects and improved oxidation resistance can be achieved. Also conceivable would be an arrangement of the intermetallic felt (2) at the rotor (4, 4a) or stator (4, 4b) opposite from the turbine blade (1) or on the platform (12) of the turbine blade (1).
