Abstract

La présente invention concerne un procédé de fabrication d’un injecteur de turbine de turbomachine par fusion laser sur lit de poudre comprenant les étapes suivantes : S1 : la fabrication d’une bride annulaire (202) coaxiale avec un axe de fabrication (X-X) normal à un plateau (3) sur lequel est placé le lit de poudre, S2 : simultanément à l’étape S1, la fabrication d’un support sacrificiel (4) agencé radialement par rapport à la bride annulaire (202), puis S3 : la fabrication d’une paroi (204) s’étendant radialement depuis une surface axiale de la bride annulaire (202), ladite paroi (204) étant venue de matière avec la bride annulaire (202) et avec le support sacrificiel (4). Figure pour l’abrégé : Fig. 1The present invention relates to a method of manufacturing a turbomachine turbine injector by laser powder bed fusion comprising the following steps: S1: manufacturing an annular flange (202) coaxial with a normal manufacturing axis (X-X) to a plate (3) on which the powder bed is placed, S2: simultaneously with step S1, the manufacture of a sacrificial support (4) arranged radially with respect to the annular flange (202), then S3: the fabricating a wall (204) extending radially from an axial surface of the annular flange (202), said wall (204) being integral with the annular flange (202) and with the sacrificial support (4).
