Patent ID: 8777582

Claim:
A component comprising: a first subcomponent comprising a nub, the first subcomponent being formed of a ceramic-based material; a second subcomponent separately formed and attached to the first subcomponent by casting a metallic material around the nub of the first subcomponent, the second subcomponent being attached to the first subcomponent by a compression fit and encapsulation of the second subcomponent on the nub of the first subcomponent; and a compliant coating system on the nub that provides thermal expansion compliance between the metallic material of the second subcomponent and the ceramic-based material of the first subcomponent, wherein the coating system comprises at least two distinct layers, a first layer of the two distinct layers directly contacting the first subcomponent and a second layer of the two distinct layers directly contacting the second subcomponent, the first layer being chemically and physically compatible with the ceramic-based material of the first subcomponent and the second layer being a transition layer between the first layer and the metallic material of the second subcomponent and being chemically and physically compatible with the metallic material of the second subcomponent.
