Protection and enhancement of thermal barrier coating by lithography

Abstract:

A method for protecting a coating on a surface of a component is provided. The method includes a coating step for coating at least a portion of the component with a ceramic slurry. A projecting step is used for projecting a pattern of light onto the component with a lithographic process to expose and solidify a ceramic layer. A removing step is used for removing unexposed portions of the ceramic slurry from the component. A heating step heats the component to sinter the ceramic layer. The ceramic layer is formed with multiple fracture planes.
