Abstract (en)

[origin: WO2022038324A1] The invention relates to a method for treating a carbon or ceramic wire (150) comprising at least forming a coating on the wire in a reaction zone (115) of a reactor (220) by heating a segment (156) of the wire in the presence of a gas phase in a microwave field, characterised in that the gas phase comprises a mixture of a diluent gas (200a; 200b) and a coating precursor in the vapour state, and in that the gas phase is formed at least by introducing the diluent gas into the reactor and mixing the introduced diluent gas with the coating precursor (140) in the reactor before the reaction zone.
