Title (EN) PROCESS FOR CONNECTING WORKPIECES USING DIFFUSION BONDING
(FR) PROCÉDÉ D’ASSEMBLAGE DE PIÈCES PAR SOUDAGE PAR DIFFUSION
(DE) VERFAHREN ZUR VERBINDUNG VON WERKSTÜCKEN MITTELS DIFFUSIONSSCHWEIßENS
Abstract:
(EN) The present invention relates to a process for connecting workpieces using diffusion bonding, according to which the pressure is increased at least once for a short period of time to achieve plastic flow, the time period of the increase in contact pressure in relation to the total duration of the diffusion process lying between 1/40 and 1/300.
(FR) La présente invention concerne un procédé d’assemblage de pièces par soudage par diffusion selon lequel la pression est augmentée au moins une fois pendant un court laps de temps de manière à obtenir un écoulement plastique, la durée de l'augmentation de la pression superficielle étant comprise entre 1/40 et 1/300 de la durée totale du procédé de diffusion.
(DE) Die vorliegende Erfindung betrifft ein Verfahren zur Verbindung von Werkstücken mittels Diffusionsschweißen, bei welchem für einen kurzen Zeitraum der Druck wenigstens einmal erhöht wird, sodass plastisches Fließen erreicht wird, wobei die Zeitdauer der Erhöhung der Flächenpressung im Verhältnis zur Gesamtdauer des Diffusionsverfahrens zwischen 1/40 und 1/300 liegt.
