Abstract
Official abstract text for this publication.
A process for depositing a coating on a continuous carbon or silicon carbide fibre from a coating precursor, includes at least heating a segment of the fibre in the presence of the coating precursor in a microwave field so as to bring the surface of the segment to a temperature enabling the coating to be formed on the segment from the coating precursor.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for depositing a coating on a continuous fibre of carbon or silicon carbide from a precursor of the coating, the process comprising: heating a segment of the fibre in the presence of the coating precursor in a microwave field so as to bring the surface of the segment to a temperature allowing the coating to form on the segment from the coating precursor, wherein: the segment of the fibre is in the presence of a gaseous phase of the coating precursor, the coating being formed by chemical vapor infiltration, the gaseous phase of the coating precursor being obtained by boiling a liquid phase of the coating precursor, the boiling resulting from contact between a hot portion of the fibre contiguous to the segment present in the microwave field and the liquid phase of the coating precursor. 2. The process as claimed in claim 1 , wherein, when heating the segment of fibre, the segment is in a first position, and the process further comprises running the fibre so as to move the segment to a second position in which the segment is out of the microwave field. 3. The process as claimed in claim 2 , wherein the running of the fibre is carried out continuously or semi-continuously. 4. The process as claimed in claim 2 , wherein the unwinding of the fibre comprises unwinding the fibre from a first mandrel and winding the fibre onto a second mandrel. 5. The process as claimed in claim 1 , wherein the coating is an interphase coating. 6. The process as claimed in claim 5 , wherein the coating comprises pyrolytic carbon, boron nitride or silicon carbide. 7. The process as claimed in claim 1 , wherein the fibre is silicon carbide having an oxygen content of less than or equal to 1 atomic percent.
