Title (EN) ADHESIVE JOINING FOR POWDER METAL COMPONENTS
(FR) LIAISON ADHÉSIVE POUR COMPOSANTS EN POUDRE MÉTALLIQUE
Abstract:
(EN) A method of joining multiple powder metal components to form a powder metal component assembly using an adhesive is disclosed. By machining at least one of the powder metal components prior to the adhesive joining, otherwise difficult to machine features can be more easily machined for less cost and at higher production rates. Unlike high temperature joining techniques, the adhesive joins the powder metal components at room temperature. This room temperature adhesive joining eliminates the thermal distortions in pre-joined machined features common to high temperature joining techniques such as brazing or welding that bring these features out of specification during joining.
(FR) La présente invention se rapporte à un procédé de liaison de multiples composants en poudre métallique pour former un ensemble de composants en poudre métallique à l'aide d'un adhésif. Grâce à l'usinage d'au moins un des composants en poudre métallique avant la liaison adhésive, des éléments qui sont autrement difficiles pour la machine peuvent être plus facilement usinés pour un moindre coût et à des taux de production supérieurs. Contrairement aux techniques de liaison à température élevée, l'adhésif relie les composants en poudre métallique à température ambiante. Cette liaison adhésive à température ambiante supprime les déformations thermiques des éléments usinés pré-reliés communs aux techniques de liaison à température élevée comme le brasage ou le soudage qui rendent ces éléments non conformes aux spécifications pendant la liaison.
