Abstract
The invention relates to a method for making a metal part that comprises a reinforcement (15) made of ceramic fibers. The method comprises the following steps: forming at least one annular-shaped insert (15) by assembling a bundle of metal-coated fibers; placing the insert into a hollow metal mold (10) such that the insert is spaced between the walls (10a, 10b) of the mold; filling the mold with a metal powder; generating vacuum in the mold and closing the same; hot isostatic compressing the assembly at a temperature and under a pressure sufficient for binding the powder particles between them and for binding the insert fibers between them; removing the mold and optionally machining to the desired shape.
Claims10
A process for manufacturing a metal part that includes at least one ceramic-fiber reinforcement, comprising:
- forming at least one insert, by assembling metal-coated ceramic fibers into a bundle;
- incorporating the insert into a hollow metal mold in such a way that the insert is spaced away from the walls of the mold;
- filling the mold with a metal powder;
- creating a vacuum in the mold and closing the mold;
- hot isostatic pressing of the assembly, at a temperature and a pressure that are sufficient to bond the metal powder particles and the metal-coated fibers of the insert;
- and
- removing the mold and, where appropriate, machining to the desired shape.
