More Information
Summary:A process for manufacturing connecting rods is provided which comprises the steps of compacting, sintering, and powder forging a powder metal comprising a carbon source and a prealloyed powder consisting essentially of iron and copper. The connecting rods made from this process have sufficient hardness and strength to be used in an engine and do not require any additional quenching or tempering. L'invention porte sur un procédé de fabrication de tiges de liaison, lequel procédé comprend les étapes de compactage, frittage et forgeage de poudre d'un métal pulvérulent comprenant une source de carbone et une poudre pré-alliée consistant essentiellement en fer et cuivre. Les tiges de liaison faites à partir de ce procédé ont des dureté et résistance suffisantes pour être utilisées dans un moteur et ne nécessitent pas de refroidissement rapide ou trempe supplémentaire.
