摘要: A method of additively manufacturing a ceramic matrix composite material includes providing a ceramic fiber and a powdery base material for a ceramic matrix composite and layer-by-layer building up the ceramic matrix material for the ceramic matrix composite by irradiating of a powder bed formed by the base material with an energy beam according to a predetermined geometry, wherein the base material is melted, solidified and adhesively joined to the ceramic fiber in that parameters of the energy beam are locally chosen such that in the contact region of the ceramic fiber and the powder bed, the ceramic fiber is only partly melted.

摘要: 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.

摘要: 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.

摘要: A film-cooling hole of gas turbine components to be cooled has an inflow section which has a constant throughflow cross section and which is adjoined by a diffuser section which has a varying throughflow cross section. The widening of the diffuser region occurs only in the direction which is perpendicular to the flow direction of the relatively hot medium.
