Abstract (en)

[origin: WO2022112684A1] One aspect of the invention relates to a method for manufacturing a dual-material turbine engine disc, comprising the following operations: providing a rough bore made of a first material, mounting the rough bore about an axis of rotation of a rotating device, rotating the rough bore, spraying a second material under solidification conditions, thereby generating a column-like or monocrystalline microstructure, which is different from the first material, on an outer surface of the rough bore in order to produce a dual-material part, and machining the dual-material part to produce a turbine engine disc. A second aspect of the invention relates to a device for implementing said method. A third aspect of the invention relates to a turbine engine disc produced using said method.
