Carbon-carbon composite including hydrophobic coating
In some examples, an article may include a carbon-carbon composite, an antioxidant in pores in a surface of the carbon-carbon composite, and a hydrophobic coating on the surface. The hydrophobic coating includes an oxide of a metal. The metal has a Pauling electronegativity of less than about 1.7. In some examples, the article may be a carbon-carbon composite brake disk that includes a carbon-carbon composite substrate defining a friction surface and a non-friction surface. The antioxidant may be a phosphate-based antioxidant, and the antioxidant may be in pores in the non-friction surface. In some examples, the hydrophobic coating is on the non-friction surface over the phosphate-based antioxidant. In some examples, the hydrophobic coating may include a majority of at least one of yttrium oxide, scandium oxide, or zirconium oxide.
