Abstract

Un procédé de matriçage d'articles frittés à base de poudres métalliques, comprend: le mélange de carbone, de ferromanganèse, et d'un lubrifiant avec une poudre de fer élémentaire compressible, le pressage du mélange ainsi réalisé pour former des articles, le frittage à haute température des articles en atmosphère réductrice et le matriçage des articles frittés à leur forme finale afin de réduire la variabilité de tolérance des articles matricés et d'éliminer pratiquement toutes les opérations secondaires.
