Abstract
A repair process for an article such as an airfoil includes providing an article that has a substrate and a ceramic barrier coating disposed on the substrate, where the ceramic barrier coating has a damaged region, abrading the damaged region to provide dimple in the ceramic barrier coating, wherein a remaining region of the ceramic barrier coating adjacent the dimple remains intact, and depositing a patch of networked ceramic nanofibers in the dimple.
