Abstract
A spline seal for a hot gas path component is provided. The spline seal may include a first metal layer and a second metal layer. The first metal layer may have a first volumetric thermal expansion coefficient. The second metal layer may be disposed adjacent the first metal layer and have a second volumetric thermal expansion coefficient. The second volumetric thermal expansion coefficient may be higher than the first volumetric thermal expansion coefficient. When the spline seal is exposed to a heat source, the first and second metal layers may deform to provide a seal between the hot gas path component and an adjacent hot gas path component.

A spline seal for a hot gas path component, the spline seal comprising:
- a first metal layer having a first volumetric thermal expansion coefficient;
- and
- a second metal layer disposed adjacent the first metal layer and having a second volumetric thermal expansion coefficient, the second volumetric thermal expansion coefficient being higher than the first volumetric thermal expansion coefficient;
- wherein when the spline seal is exposed to a heat source, the first and second metal layers deform to provide a seal between the hot gas path component and an adjacent hot gas path component.
A spline seal for a hot gas path component, the spline seal comprising:
- a first metal layer having a first volumetric thermal expansion coefficient;
- and
- a second metal layer disposed adjacent the first metal layer and having a second volumetric thermal expansion coefficient, the second volumetric thermal expansion coefficient being higher than the first volumetric thermal expansion coefficient;
- wherein when the first metal layer is exposed to a cooling medium flow and the second metal layer is exposed to a hot gas path flow, the first and second metal layers deform, causing the spline seal to deform from a first substantially flat profile to a second substantially U-shaped profile and provide a seal between the hot gas path component and an adjacent hot gas path component.
