Title
(EN) METHOD OF MANUFACTURING OF A SINTERED METAL FIBER MEDIUM
(FR) PROCEDE DE FABRICATION D'UN OBJET CONTENANT DES FIBRES METALLIQUES FRITTEES
Abstract
(EN)
The invention relates to a method for manufacturing a sintered metal fiber medium, comprising the steps of: providing metal fibers; making a slurry comprising the metal fibers and a binding agent by mixing the metal fibers and the binding agent, possibly with a solvent; casting a layer of the slurry on a support using an applicator; solidifying this slurry, providing a foil comprising the metal fibers and the binding agent; debinding the binding agent in the foil and sintering the metal fibers.
(FR)
L'invention concerne un procédé destiné à la fabrication d'un objet contenant des fibres métalliques frittées. Ce procédé consiste : à fournir des fibres métalliques ; à produire une suspension épaisse renfermant les fibres métalliques et un agent liant en mélangeant les fibres métalliques et l'agent liant, de préférence avec un solvant ; à former une couche de la suspension épaisse sur un support à l'aide d'un applicateur ; à solidifier cette suspension épaisse pour obtenir une pellicule comprenant les fibres métalliques et l'agent liant ; à séparer l'agent liant et la pellicule et à fritter les fibres métalliques.
