Oxidation protection of a porous material component containing carbon, by impregnation with an aqueous medium, utilizes an impregnation composition containing a compound of phosphorus (P), elementary titanium (Ti) and boron (B) or a compound 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 that catalyses the oxidation of the carbon, at least one association of the type P-O-Ti-M bound by boron oxide (B2O3) and trapping the element M. |
