Abstract: The invention concerns a method of repairing cracks in a metal component (1), in particular a guide blade (10) of a gas turbine, said component (1) having a crack (2). According to the invention, the crack (2) in the component (1) is made into a groove (3), and at least one filler member (4) matching the shape of the groove (3) is inserted therein and rigidly connected to the component (1). Preferably, the groove (3) is formed by one or a plurality of straight segments (5) into each of which is introduced a rod-shaped filler member (4) corresponding to the component (1) from the metallurgical aspect. The invention further concerns a turbine blade (10), in particular a gas turbine guide blade, comprising a groove (3) filled with a filler member (4).

Abstract: The invention relates to a method for producing a gas turbine vane, comprising the following steps: producing, especially casting, a hollow, supporting metal vane body (1); producing a plurality of especially stud-like raised elements (5) on an outer surface of a blade (3) of a metal vane body (1), boring impact cooling bores (8) between said raised elements (5), from the outer surface to the hollow space (4) inside the metal vane body (1), applying a coating (11) which fills the intermediate spaces (7) between the raised elements (5) and seals the impact cooling bores (8), said coating consisting of a heat-resistant, removable material, applying a cover layer (9) which adheres to the bright metallic top surfaces (6) of the raised elements (5), and removing the material in the intermediate spaces (7) between the raised elements (5) of the metal vane body (1) and the cover layer (9). The invention also relates to a gas turbine vane produced according to this method.

Abstract: 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.

Abstract: The radiator (2) has radiator elements (12) arranged in a flow channel (6) that is subjected with fluid to be exhalable or vaporizable by a functioning device (16). The surface of cooling elements has hydrophilic character in a certain partial area for the formation of the fluid film. One of the radiator elements has a base plate comprising a hydrophilic surface coating. The radiator elements have a base plate that is provided with a hydrophilic surface layer according to Sol-gel method.
