A tip material for a turbine blade or for repairing a damaged tip of a turbine blade having a metallic coating, the material used for the tip is equivalent in composition to the metallic coating material used for the turbine blade. Also disclosed is a method of manufacturing or repairing a tip of a turbine blade having a metallic coating by reforming the blade tip with a material equivalent in composition to the metallic coating material used for the turbine blade by bonding the material to the damaged tip.

Tip material for a turbine blade and method of manufacturing or repairing a tip of a turbine blade

In a soldering process for treating tears, recesses, or other material defects in the surface of thermally and mechanically highly stressed components of gas turbines, a nickel foam is applied together with the soldering powder, which can also be mixed with another filler. After this, a heat treatment of the soldering process is performed.

Method for repairing a gas turbine component

Process of plugging cooling holes (,) of a gas turbine component (,) with an external surface (,), having a cavity (,) and a plurality of cooling holes (,) before coating the gas turbine component (,), characterised in that mask material (,) is applied to the external surface (,) of the component (,) while a fluid is forced through the cooling holes (,), the mask material (,) is thickened while the fluid is forced through the cooling holes (,), the cooling holes (,) are plugged with plug material (,), the mask material (,) is removed from the external surface (,) of the component (,), the component (,) and the plugged cooling holes (,) are coated and the plug material (,) is removed from the cooling holes (,).
