METHOD OF PROVIDING ANTI-OXIDATION PROTECTION FOR A COMPOSITE MATERIAL CONTAINING CARBON, AND A MATERIAL PROTECTED THEREBY |
摘要 |
A composite material containing carbon is protected against oxidation by forming, on the composite material, an inner layer, an intermediate layer containing boron or a boron compound, and an outer layer of silicon carbide. The inner layer formed on the composite material before the intermediate layer is formed, is made of a refractory carbide that does not contain boron and that is at least 60 microns thick, said inner layer insulating the intermediate layer from the carbon contained in the composite material.
