Method of protecting carbon-carbon composite brake disc against migration of anti-oxidant composition through the porosity of the composite brake disc. The method starts with a porous carbon-carbon composite brake disc, and densifies it to a density of 1.70 grams per cubic centimeter or higher. The densified brake disc is then machine to the required dimensions. The pores in the densified brake disc are closed by subjecting it to CVD / CVI processing employing (i) a gaseous feedstock comprising natural gas spiked with 10 to 25% of a more reactive gas, and / or (ii) a temperature in the range of 1100° C. to 1500° C., and / or (iii) a gas pressure in the range 10 to 100 torr, and / or (iv) a gas flow rate of 300 cc / min to 450 cc / min. CVD / CVI processing carried out using these parameters deposits carbon within and closes the pores of the surface area of the carbon-carbon composite brake disc.
