| 摘要 | A method of treating ceramic fibers based on metal carbide, the method including a first reagent gas heat treatment performed with at least one first reagent gas of the halogen type that chemically transforms the surface of the fiber to obtain a surface layer constituted mainly of carbon, and a second reagent gas heat treatment performed with at least one second reagent gas that eliminates the surface layer formed during the chemical transformation. | ||

| 主权项 | 1. A method of treating ceramic fibers based on metal carbide, the method comprising performing a first reagent gas heat treatment with at least one first reagent gas of the halogen type that chemically transforms the surface of the fiber to obtain a surface layer constituted mainly of carbon, and performing a second reagent gas heat treatment with at least one second reagent gas that eliminates the surface layer formed during the chemical transformation, wherein the treated fibers are Si—C—O fibers. | ||
