| description | The invention relates to a method for manufacturing a shell mold for the production by lost-wax casting of bladed elements (1) of an aircraft turbine engine, including the following steps: a) creating an assembly (200) including a wax pattern (100) as well as a device for forming a cup for pouring metal (32b) and having an end surface (40a); b) depositing a hot wax coating layer on at least one portion of the end surface (40a); c) forming the shell mold around the assembly (200). In addition, the method includes, between steps b) and c), the implementation of a step of structuring the coating layer intended for reinforcing the adhesion between said layer (46) and the shell mold, and including the production of recesses (62) and projections (60) on the still-malleable coating layer.
L'invention concerne un procédé de fabrication d'une carapace pour la réalisation par moulage à cire perdue d'éléments aubagés (1) de turbomachine d'aéronef, comprenant les étapes suivantes : a) réalisation d'un ensemble (200) comprenant un modèle en cire (100) ainsi qu'un dispositif destiné à former un godet de coulée de métal (32b) et présentant une surface d'extrémité (40a); b) dépôt d'une couche d'enrobage en cire chaude sur au moins une partie de la surface d'extrémité (40a); c) formation de la carapace autour de l'ensemble (200). De plus, le procédé comprend, entre les étapes b) et c), la mise en uvre d'une étape de structuration de la couche d'enrobage visant à renforcer l'adhérence entre cette couche (46) et la carapace, et comprenant la réalisation de creux (62) et de saillies (60) sur la couche d'enrobage encore malléable. |
