Abstract

Procédé d ’ impression d e riblet s sur la surface d’une pièce et pièce aéronautique comportant des riblets imprimés par un tel procédé Un aspect de l’invention concerne un procédé d’impression de riblets (50) sur la surface d’une pièce aéronautique (10), comportant les opérations suivantes : application (110) d’un revêtement anti-corrosion (12) sur la surface de la pièce,application (120) d’un revêtement de protection (20), lisse, sur la surface de la pièce,installation (130), sur la surface de la pièce recouverte du revêtement de protection, d’une contreforme (30) comportant des empreintes (45) de riblets,installation (140), sur la contreforme (30), d’une plaque de pression (40)application (150) d’une pression prédéfinie sur la plaque de pression (40) pendant une durée prédéterminée, etretrait de la plaque de pression (40) et de la contreforme (30) de sorte à obtenir des riblets (50) imprimés sur le revêtement de protection (20) recouvrant la surface de la pièce. Un autre aspect de l’invention concerne une pièce aéronautique (10) comportant une surface au moins partiellement recouverte de riblets imprimés selon ce procédé. Figure à publier avec l’abrégé : Figure 3Method for printing riblets on the surface of a part and aeronautical part comprising riblets printed by such a process. One aspect of the invention relates to a method for printing riblets (50) on the surface of an aeronautical part (10), comprising the following operations: application (110) of an anti-corrosion coating (12) on the surface of the part, application (120) of a protective coating (20), smooth, on the surface of the part, installation (130), on the surface of the part covered with the protective coating, a counterform (30) comprising imprints (45) of riblets, installation (140), on the counterform (30), a pressure plate (40) application (150) of a predefined pressure on the pressure plate (40) for a predetermined duration, and removal of the pressure plate (40) and the counterform (30) so as to obtain riblets (50) printed on the protective coating (20) covering the surface of the part. Another aspect of the invention relates to an aeronautical part (10) comprising a surface at least partially covered with riblets printed according to this process.
