Abstract[German]
Die Erfindung betrifft ein Verfahren zum Glätten wenigstens eines Oberflächenbereichs eines Kanals (12) eines additiv gefertigten Bauteils (10) eines Flugtriebwerks, bei welchem wenigstens ein chemisches Abtragmittel (20) durch den Kanal (12) geleitet wird, welches ein Material des Bauteils (10) abträgt, bis eine vorbestimmte Oberflächenqualität zumindest im zu glättenden Oberflächenbereich erreicht ist. Das chemische Abtragmittel (20) umfasst zumindest Ammoniumbifluorid.[English]
The invention relates to a method for smoothing at least one surface region of a duct (12) of an additively manufactured component (10) of an aircraft engine, in which at least one chemical removal agent (20) is passed through the duct (12) and removes a material of the component (10) until a predetermined surface quality is achieved at least in the surface region to be smoothed. The chemical removal agent (20) comprises at least ammonium bifluoride.[French]
L'invention concerne un procédé de lissage d'au moins une région de surface d'un conduit (12) d'un composant (10) fabriqué de manière additive d'un moteur d'aéronef, dans lequel au moins un agent d'élimination chimique (20) est passé à travers le conduit (12) et élimine un matériau du composant (10) jusqu'à ce qu'une qualité de surface prédéterminée soit obtenue au moins dans la région de surface à lisser. L'agent d'élimination chimique (20) comprend au moins du bifluorure d'ammonium.
