Abstract

Carbon composite materials of increased resistance to oxidation are produced by heating a porous carbon composite material to an elevated temperature in a reaction chamber and introducing into said chamber a gas mixture comprising a decomposable boron-containing gas and a diluent and effecting deposition of boron as a solid on the walls of the pores of said composite as a consequence of said boron-containing gas decomposing.
