Abstract

L’invention concerne un composant de turbomachine (1) de turbomachine, comportant une paroi (10) ayant au moins un perçage (3) de refroidissement en oblique d’un angle (α) prédéterminé vis-à-vis de la direction (Z) d’épaisseur, le perçage (3) de refroidissement comprenant une portion de dosage (31) délimitée par une surface de dosage (310), et une portion de diffusion (32) délimitée par une surface de diffusion (320). L’invention est caractérisée en ce que la surface de diffusion (320) est raccordée à la surface de dosage (310) par une surface de liaison (35), qui est inclinée par rapport à une partie aval (312) de la surface de dosage (310) et par rapport à une partie aval (323) de la surface de diffusion (320), de sorte à ce que la surface de liaison (35) forme une marche à la jonction entre celles-ci.
