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.

Device and method for removing coating material from openings in a part

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.

Device and method for analyzing the surface of parts having cooling fluid openings

Introducing a through hole into a substrate () before coating, and performing the removal thereafter, shortens the machining times for producing a through hole () with a diffuser () and also subjects the intermediate layers to less stress.

Method for the new production of through holes in a layer system

A process for reopening cooling-air holes by a laser in order to remove coat down is provided. A nanosecond laser is provided and used for reopening the holes, wherein pulse times between 1 &#x3bc;s and 20 &#x3bc;s and a pulse frequency between 20 kHz and 40 kHz provided by the nanosecond laser are used.

Reopening of cooling-air bores using a nanosecond laser in the microsecond range

During the coating of a component including cooling-air holes, it is necessary, when remachining the coated cooling-air holes, to determine the correct alignment of the cooling-air row. A process is provided in that at least two cooling-air holes are kept clear by a masking material during the coating and the alignment of the cooling-air row is effected on the basis of these two unclosed cooling-air hole.
