Abstract
A method for treating a carbon or ceramic yarn includes forming a coating on the yarn in a reaction zone of a reactor by heating a segment of the yarn in the presence of a gas phase in a microwave field, wherein the gas phase includes a mixture of a diluent gas and a coating precursor in the vapor state, and wherein 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 in the reactor before the reaction zone.
