Abstract: Engine structures and methods of forming the engine structures are provided herein. In an embodiment, an engine structure includes a silicon-based ceramic-containing substrate having an in-tolerance surface and one or more barrier layers disposed on the in-tolerance surface of the ceramic-containing substrate. The ceramic-containing substrate includes a bulk zone and a gradient zone. The bulk zone includes a first bulk material. The gradient zone includes the first bulk material and a second material that is different from the first bulk material. The gradient zone has a gradient of increasing concentration of the second material from the bulk zone to the in-tolerance surface of the ceramic-containing substrate.
