Abstract
An airfoil used in a gas turbine engine exposed to high temperatures, the airfoil having a TBC layer that includes fibers of reinforcing material to add strength to the layer of TBC. The fibers are made from a similar material in which the airfoil is made from to withstand the high temperatures, and have a diameter of about 0.1 mm in order that a thin layer of TBC can completely cover and embed the fibers within the layer.
Claims7
An airfoil used in a turbine section of a gas turbine engine, the airfoil including a TBC applied on the surface, the improvement comprising:
- a fibrous reinforcement embedded in the TBC layer to provide reinforcement to the layer and prevent spalling.
A process of forming a TBC layer on an airfoil used in a gas turbine engine, the process comprising the steps of:
- providing for an airfoil formed of a substrate;
- applying a bond coat to the substrate;
- placing a plurality of reinforcement fibers on the bond coat;
- and,
- applying a TBC layer over the fibers such that the fibers are completely embedded within the TBC layer.
