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.
Claims19
A wear-reducing coating system for a substrate, comprising:
- an innermost layer disposed on a substrate;
- an outermost layer disposed on the innermost layer, wherein 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;
- and
- wherein the substrate is a split ring casing of a high pressure compressor for a gas turbine engine.
A method of applying a wear-reducing coating to a substrate, comprising:
- depositing an innermost layer on a substrate;
- depositing an outermost layer on the innermost layer by atomic layer deposition, wherein the innermost layer has a higher load-carrying capacity than the outermost layer and the outermost layer has a lower coefficient of friction than the innermost layer;
- and
- wherein the substrate is a split ring casing of a high pressure compressor for a gas turbine engine.
A method of applying a coating to a split ring casing for a high pressure compressor, comprising:
- depositing a coating onto a split ring casing for a high pressure compressor by atomic layer deposition, the split ring casing including at least one slot configured to receive a seal, wherein the coating is deposited in the slot, the coating including a layer of a solid lubricant.
