Abstract
A method for densifying a metal part, including the following steps: coating the metal part with a leak-tight material, compacting the coated metal part under an isostatic pressure of a fluid, removing the coating from the metal part, and performing final annealing of the metal part.
Claims13
A method for densifying a porous metal part comprising at least one hollow portion, the method comprising the following steps:
- a preliminary step of filling said at least one hollow portion with a filler metal that is introduced in liquid form, then solidifying this filler metal, the filler metal having a melting point below the melting point of the metal part;
- coating the metal part with a leak-tight material;
- compacting the coated metal part under an isostatic pressure of a fluid;
- removing the coating from the metal part;
- removing the filler metal, and;
- and
- final annealing of the metal part.
