ABSTRACT:
The oxidation protection for a surface of a carbon/carbon composite substrate having a primary protective coating previously formed thereon is improved by applying to said surface a layer of a coating material comprising titanium diboride, colloidal silica, and an intermetallic compound, e.g., silicon carbide. The primary coating can be a boronated silicon carbide coating.
