Title (EN) METHOD FOR PROCESSING CERAMIC FIBRES
(FR) PROCEDE DE TRAITEMENT DE FIBRES CERAMIQUES
Abstract:
(EN) The invention relates to a method for processing metal carbide ceramic fibres (10), including a first reactive gaseous-phase thermal processing (S1) of the halogen type producing a superficial layer (12) mainly containing carbon by chemical conversion of the surface fibres, and a second reactive gaseous-phase thermal processing (S2) carried out with at least one second reactive gas for removing the superficial layer formed at the surface during the chemical conversion.
(FR) Procédé de traitement de fibres céramiques (10) à base de carbure métallique comprenant un premier traitement thermique en voie gazeuse réactive (S1) réalisé avec au moins un premier gaz réactif de type halogène formant, par transformation chimique de la fibre en surface, une couche superficielle (12) constituée majoritairement de carbone et un deuxième traitement thermique en voie gazeuse réactive (S2) réalisé avec au moins un deuxième gaz réactif éliminant la couche superficielle formée en surface lors de la transformation chimique.
