Abstract: An air foil includes a body and a filler. The body may include a chamber formed therein and includes a first metallic material. The filler may at least partially occupy the chamber of the body and may include a second metallic material. The second metallic material may have a comparatively more negative electrode potential than the first metallic material.

Abstract: A method for forming a self-healing ceramic matrix composite (CMC) component includes depositing a first self-healing particulate material in a first region of a CMC preform of the CMC component and depositing a second self-healing particulate material having a different chemical composition than the first self-healing particulate material in a second region of the CMC preform distinct from the first region.
