Abstract
Each friction face of a brake disk (10) is masked (plates 40, 46) to isolate and seal the exterior from liquids, and the disk is immersed in a bath (30) of impregnating composition containing at least one substance which can form a protective layer against oxidation. Impregnation is effected by establishing a pressure difference between the pressure at the exterior of the exposed surfaces of the immersed brake disk (10) and the pressure inside the internal open pore space of the brake disk, without completely evacuating the latter, to force the impregnating composition to penetrate into the internal open pore space of the disk to a certain depth from the exposed surfaces, to form an internal oxidation protection. The pressure difference is adjusted depending on the desired depth of penetration of the impregnating composition into the internal open pore space.
