| Abstract: A coated carbon-carbon composite material with multiple ceramic layers to
provide oxidation protection from ultra-high-temperatures, where if the
carbon-carbon composite material is uninhibited with B.sub.4C particles,
then the first layer on the composite material is selected from ZrB.sub.2
and HfB.sub.2, onto which is coated a layer of SiC coated and if the
carbon-carbon composite material is inhibited with B.sub.4C particles,
then protection can be achieved with a layer of SiC and a layer of either
ZrB.sub.2 and HfB.sub.2 in any order. |
