CARBON-CARBON COMPOSITE INCLUDING ANTIOXIDANT COATING
The invention relates to a carbon-carbon composite including an antioxidant coating. An article including carbon-carbon composite substrate is treated with an antioxidant coating prior to use in an oxidizing environment. The antioxidant coating is configured to reduce oxidation at an external surface of the C-C composite and reduce ingress of oxidants into pores or other open passages defined by the C-C composite substrate to avoid internal oxidation. The 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 is disposed on at least a portion of the bond coat. The antioxidant coating includes ytterbium disilicate and a sintering aid.
本发明题为“包括抗氧化剂涂层的碳‑碳复合物”。包括碳‑碳复合基底的制品可在用于氧化环境中之前用抗氧化剂涂层处理。抗氧化剂涂层可被配置成减少C‑C组合物的外表面处的氧化并且减少氧化剂进入由C‑C复合基底限定的孔或其他开放通道中以避免内部氧化。示例性制品包括C‑C复合基底、粘结涂层和抗氧化剂涂层。C‑C复合基底限定摩擦表面和非摩擦表面。粘结涂层被设置在非摩擦表面上。抗氧化剂涂层可被设置在粘结涂层的至少一部分上。抗氧化剂涂层可包含二硅酸镱和烧结助剂。
