PROCÉDÉ DE FABRICATION D'UNE PIÈCE PRES-DES-COTES (NEAR NET SHAPE OU NNS) DE FORME COMPLEXE PAR FRITTAGE SOUS CHARGE
The invention relates to a method for manufacturing a near net shape (NNS) component of complex shape using pressure-assisted sintering from a preform produced according to a first method of manufacture. This method of manufacturing a component using pressure-assisted sintering is characterized in that it comprises a first step of producing a preform by agglomerating particles of particle size D50 less than 15 µm in a binding die, the preform forming a non-porous and non-debound solid monolithic component, and a second step of heat-treating said solid and non-porous preform under pressure.
