PROTECTION AND ENHANCEMENT OF THERMAL BARRIER COATING INTEGRITY BY LITHOGRAPHY

A method for protecting a coating on a surface of a component is provided. The method includes a coating step that coats at least a portion of the component with a ceramic slurry. A projecting step projects a pattern of light onto the component with a lithographic process to expose and solidify a ce...

Beschreibung
Zusammenfassung:	A method for protecting a coating on a surface of a component is provided. The method includes a coating step that coats at least a portion of the component with a ceramic slurry. A projecting step projects a pattern of light onto the component with a lithographic process to expose and solidify a ceramic layer. A removing step removes unexposed portions of the ceramic slurry from the component. The ceramic layer comprises multiple stress raising elements or multiple anchoring elements having a rectangular, trapezoidal or dovetail shape.
