Abstract

La présente invention concerne un procédé de fabrication d'un secteur (4) de redresseur annulaire d'un compresseur ou de distributeur annulaire de turbine pour turbomachine, comprenant un élément abradable à structure en nid d'abeilles (5). Ce procédé est remarquable en ce qu'il consiste à fabriquer ledit secteur (4) par fabrication additive par fusion laser sur un lit de poudre, de sorte qu'il soit monobloc, en ce que l'élément abradable à structure en nid d'abeilles (5), qui comprend une pluralité d'alvéoles (50) hexagonales, est fabriqué à l'horizontale par rapport à un plateau de fabrication horizontal, en ce que les deux parois horizontales (51) et les quatre parois latérales (52) de chaque alvéole (50) sont fabriquées respectivement par paramétrie laser volumique et par paramétrie laser linéaire, et en ce que pour la formation desdites parois horizontales (51) et latérales (52), le faisceau laser est réglé de façon à fournir une densité d'énergie linéique inférieure à celle utilisée pour fabriquer le reste des parties du secteur (4).
