Abstract
An apparatus is provided for a gas turbine engine. This gas turbine engine apparatus includes a hot section structure of the gas turbine engine. The hot section structure is configured with a plurality of surfaces respectively forming boundaries of a gas path through the hot section structure. The surfaces include a first surface and a second surface. The hot section structure includes metal and thermal barrier material. The first surface is formed by the metal. The second surface is formed by the thermal barrier material.
Claims15
An apparatus for a gas turbine engine, comprising:
- a hot section structure of the gas turbine engine;
- the hot section structure configured with a plurality of surfaces respectively forming boundaries of a gas path through the hot section structure, the plurality of surfaces including an uncoated first surface and a second surface;
- and
- the hot section structure including metal and thermal barrier material, the uncoated first surface formed by the metal, and the second surface formed by the thermal barrier material;
- wherein the uncoated first surface is formed by the metal such that the metal forming the uncoated first surface is configured to be directly exposed to hot gas flowing through the gas path;
- and
- wherein the hot section structure comprises a vane, and the thermal barrier material forms at least a portion of a trailing edge of the vane.
