摘要：
Process for the production of a composite material protected against oxidation and the material obtained by the process. The invention relates to a process for the production of a material incorporating a composite body on which an aluminum nitride layer is directly deposited and then a tight layer of a refractory oxide in order to ensure its protection against environmental oxidation. The aluminum nitride layer is attached to the composite by an aluminum carbide layer. The oxide layer is an alumina layer.
