Abstract
The method for manufacturing a blade (32) of a turbomachine (100) comprises: —manufacturing a part (4) comprising an air flow path zone (10) and a layer (20) covering the zone, the layer having cavities (21) forming a periodic pattern, the manufacture taking place by injecting a mixture comprising a binder and a power; —removing a larger part of the binder from the part; —sintering the part, and —removing the layer (20) from the part to obtain the blade (32).
Claims22
A method for manufacturing a turbomachine blade, the method comprising:
