Abstract
A component assembly includes a support structure, a ceramic substrate mounted to the support, and a foam-like coating adhered to one of the support structure and the ceramic substrate. The foam-like coating engages the other of the support structure and the ceramic substrate.
Claims18
A component assembly comprising:
- a support structure, wherein the support structure is a rotor having a slot;
- a ceramic substrate mounted to the support;
- a blade including a root that provides the ceramic substrate, the root received in the slot;
- and
- a foam-like coating having a porosity of less than 30% that is adhered to one of the support structure and the ceramic substrate, and the foam-like coating engaging the other of the support structure and the ceramic substrate.
2 more elements
A method of manufacturing a component assembly comprising a blade including a root that provides the ceramic substrate, the method comprising the steps of:
- depositing ceramic onto a rigid ceramic substrate to produce a flexible foam-like coating having a porosity of less than 30%;
- and
- installing the root into a rotor slot, wherein the foam-like coating is configured to transfer a force from a high point on the rotor slot to the ceramic substrate by flexing without cracking a surface of the root.
