Abstract: A method and device for coating a component wherein the cooling fluid ducts contained in the component have to be reopened following the coating step. The component has a first region and a second region, where the first region includes at least one cooling fluid opening having an adjoining cooling fluid channel and where the first region is to be coated with a coating material which is not to be applied in the second region.

Abstract: A method for producing a plurality of holes in a curved surface, wherein the individual holes are removed layer by layer, the first layers to be removed of the holes being arranged at different distances in a Z-direction of the laser, the holes each being processed in a specific focal position, wherein only the holes detected from the same focal position are processed.

Abstract: A method for coating a part having a surface that has cooling fluid openings that adjoin cooling fluid ducts inside the part. A device analyzes the surface of a part having a surface that has cooling fluid openings which adjoin cooling fluid ducts inside the part, the device being usable in the aforementioned method. The disclosed device and/or the disclosed method is used during the manufacturing and/or overhauling of parts of a turbomachine.

Abstract: Through_holes having a high contour accuracy are produced by the multiple use of a nanosecond laser without that the interface between the ceramic layer and the substrate is damaged.

Abstract: A method for producing through-holes in a wall of a component, by laser radiation is provided, that includes a wall delimiting a cavity in which a protection agent is provided that can be liquefied when heated. According to the method, through-holes are successively produced in the wall of the component in a plurality of defined points, two directly subsequent through-holes being produced such that a through-hole is produced in a predetermined point and the next through-hole is produced in an additional point which is further away from the predetermined point than at least two, in particular three or more omitted points that are closer to the predetermined point, and/or are produced such that a through-hole is produced in a predetermined point and the next through-hole is produced an additional point.
