Abstract: A wear-reducing coating system for a substrate includes an innermost layer disposed on a substrate and an outermost layer disposed on the innermost layer. The innermost layer has higher load-carrying capacity than the outermost layer and the outermost layer has a lower coefficient of friction than the innermost layer. A method of applying a wear-reducing coating to a substrate and a method of applying a coating to a split ring casing for a high pressure compressor are also disclosed.

Abstract: A sealing system includes a shaft, a rotor configured to rotate with respect to the shaft, and a carbon-carbon composite seal ring arranged around the shaft such that it seals against the rotor. The carbon-carbon composite seal ring includes a monoaluminum phosphate binder layer disposed on at least one surface of the carbon-carbon composite seal ring and a ceramic layer disposed over the monoaluminum phosphate binder layer on the least one surface of the carbon-carbon composite seal ring. A method of manufacturing a seal is also disclosed.
