The present invention concerns a method of producing powder-metallurgical compacted components, which during subsequent processing are split into individual parts mating in pairs, sintered and optionally heat-treated and remated. According to the process, an iron-based powder is compacted, the obtained green body is fracture-split into at least two parts, which are subsequently sintered and optionally heat-treated. The obtained sintered parts are then remated.

L'invention porte sur un procédé de réalisation de composants de poudre métallique compactée qui au cours des phases postérieures du traitement sont divisés en pièces séparées appariées puis frittées et éventuellement soumises à un traitement thermique puis réappariées. Le procédé consiste à compacter de la poudre à base de fer puis l'ébauche crue est fractionnée en au moins deux pièces qui sont ensuite frittées puis éventuellement soumises à un traitement thermique, les pièces frittées ainsi obtenues sont ensuite réappariées.
