According to the invention, a component consisting of a porous material containing carbon, especially a composite material C/C, is protected against oxidation by being impregnated by a composition in an aqueous medium containing at least one compound of phosphorus, elementary titanium, boron, or a composite of boron other than titanium diboride, in order to form, in the presence of oxygen and at least one alkaline or alkaline-earth element M which is a catalyst of the oxidation of carbon, at least one P-0-Ti-M-type association which is bound by boron oxide B<SUB>2</SUB>O<SUB>3</SUB> and traps the element M. |
