Patent ID: 6896968

Claim:
A carbon-containing component comprising a protective coating, wherein the carbon-containing component is selected from the group consisting of graphite, amorphous carbon, carbon fibers and carbon-carbon composites; and wherein the protective coating comprises a material selected from the group consisting of: silicon oxycarbide (SiO x C y ); silicon oxynitride (SiO x N z ); silicon carbonitride (SiC y N z ); and silicon oxycarbonitride (SiO x C y N z ); wherein x<2, y<1 and z<4/3, and at least two of x, y, and z are greater than zero in each of said materials; wherein the carbon (C) in the protective coating is chemically bound, and wherein the protective coating is deposited by means of chemical vapor deposition using methylsilane and nitrous oxide.
