Title (EN) HYBRID PRE-SINTERED PREFORM, GREEN PREFORM, AND PROCESS
(FR) COMPRIMÉ HYBRIDE PRÉFRITTÉ, COMPRIMÉ CRU ET PROCÉDÉ
Abstract:
(EN) A process includes agitating at least one core of a core alloy together with a braze binder to form at least one coated core comprising the at least one core coated with a first layer of the braze binder. The process also includes agitating the at least one coated core together with a powder composition comprising a first metal powder of a first alloy and a second metal powder of a second alloy to form a green preform having a first powder composition layer of the first alloy and the second alloy. The process further includes sintering the green preform to form at least one hybrid pre-sintered preform. A green preform includes a core, a first layer of a braze binder coated on the core, and a powder composition coated on the first layer. A hybrid pre-sintered preform includes a core and a first layer sintered to the core.
(FR) Cette invention concerne un procédé, comprenant l'agitation d'au moins un noyau d'un alliage de noyau conjointement avec un liant de brasage pour former au moins un noyau enrobé comprenant le(s) noyau(x) enrobé(s) d'une première couche du liant de brasage. Le procédé comprend également l'agitation du/des noyau(x) enrobé(s) conjointement avec une composition de poudre comprenant une première poudre métallique d'un premier alliage et une seconde poudre métallique d'un second alliage pour former un comprimé cru ayant une première couche de composition de poudre du premier alliage et du second alliage. Le procédé comprend en outre le frittage du comprimé cru pour former au moins un comprimé hybride préfritté. Un comprimé cru comprend un noyau, une première couche d'un liant de brasage déposée sur le noyau, et une composition de poudre déposée sur la première couche. Un comprimé hybride préfritté comprend un noyau et une première couche frittée sur le noyau.
