Title
(EN) IN SITU SYNTHESIS, DENSIFICATION AND SHAPING OF NON-OXIDE CERAMICS BY VACUUM ADDITIVE MANUFACTURING TECHNOLOGIES
(FR) SYNTHÈSE, DENSIFICATION ET MISE EN FORME IN SITU DE CÉRAMIQUES DE NON OXYDES PAR DES TECHNOLOGIES DE FABRICATION ADDITIVE SOUS VIDE
Abstract
(EN)
A vacuum additive manufacturing process enabling to obtain, through a single-step process, the synthesis, controlled densification and shaping of non-oxide materials as well as composite materials containing non-oxide as matrices or reinforcements, in porous as well as fully dense ceramic components, with a tailored nano-micro-macrostructure.
(FR)
L'invention concerne un procédé de fabrication additive sous vide permettant d'obtenir, par un procédé en une seule étape, la synthèse, la densification controlée et la mise en forme de matériaux de non oxydes ainsi que de matériaux composites contenant des non-oxydes comme matrices ou renforts, dans des éléments céramiques poreux ainsi que des éléments céramiques entièrement denses, présentant une nano-micro-macrostructure personnalisée.
