Method for manufacturing a metallurgical part by hot compaction of metal powder

摘要

The invention presents a method of manufacturing a metallurgical part by hot compaction of metal powder comprising: a first step of manufacturing a sealed metal container a second step of depositing a coating on the interior surface of the container a third step of filling said container with metal powder a fourth step of degassing the container by vacuuming a fifth step of applying a temperature rise and pressure cycle of the sealed container filled with metal powder for hot isostatic compression a sixth step of separation of the body and the container characterized in that the said step of manufacturing a metal container consists in producing a hollow structure having rupture zones extending in a separation plane as well as external traction extensions arranged on either side of said separation plan.
