    摘要: The invention relates to a method of manufacturing a gas-trubine blade and to a turbine blade. First, a hollow, supporting metal blade body is made, in particular by casting, with a multiplicity of, in particular peg-like, elevations on an outer surface of a blade airfoil of the metal blade body. Impact cooling bores are bored between the elevations from the outer surface to the hollow interior space of the metal blade body. A coating is applied which fills the intermediate spaces between the elevations and closes the impact cooling bores. The coating is made of a heat-resistant, removable material. Then, a covering coat is adhered to the metallically bright top sides of the elevations, and the material in the intermediate spaces between the elevations of the metal blade body and the covering coat is then removed.

    摘要: Component repair process, in which a loss of wall thickness is repaired just by a standard coating, results in a component with a layer which has properties that are less than optimum in the repaired region at elevated temperatures. The process according to the invention includes a plastic deformation and heat treatment of the layer, so that it is converted into a coarse-grained microstructure.
