CMAS barrier coating for a gas turbine engine having a reactive material that reacts with a layer of environmental contaminant compositions and method of applying the same

Abstract:

A coated component, along with methods of its formation, restoration, and use, is provided. The coated component may include a substrate defining a surface; a thermal barrier coating on the surface of the substrate; a layer of environmental contaminant compositions (e.g., CMAS) on the thermal barrier coating; and a chemical barrier coating on the layer of environmental contaminant compositions.
