METHOD FOR PROCESSING CERAMIC FIBRES

摘要

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.
