Abstract: An article including carbon-carbon composite substrate may be treated with an antioxidant coating prior to use in an oxidizing environment. The antioxidant coating may be configured to reduce oxidation at an external surface of the C—C composition and reduce ingress of oxidants into pores or other open passages defined by the C—C composite substrate to avoid internal oxidation. An example article includes a C—C composite substrate, a bond coat, and an antioxidant coating. The C—C composite substrate defines a friction surface and a non-friction surface. The bond coat is disposed on the non-friction surface. The antioxidant coating may be disposed on at least a portion of the bond coat. The antioxidant coating may include ytterbium disilicate and a sintering aid.
