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.

Abstract: Methods for depositing wear resistant NiW plating systems on metallic components are provided. In various embodiments, the method includes the step or process of preparing a NiW plating bath containing a particle suspension. The NiW plating bath is prepared by introducing wear resistant particles into the NiW plating path and adding at least one charged surfactant. The first type of wear resistant particles and the first charged surfactant may be contacted when introduced into the NiW plating bath or prior to introduction into the NiW plating bath. The at least one charged surfactant binds with the wear resistant particles to form a particle-surfactant complex. The wear resistant NiW plating system is then electrodeposited onto a surface of a component at least partially submerged in the NiW plating bath. The resulting wear resistant NiW plating system comprised of a NiW matrix in which the wear resistant particles are embedded.
