Abstract

A gas turbine engine component coated with a thermal barrier coating that includes a metallic bond coat and a ceramic top coat is repaired by removing the ceramic top coat from an engine-run gas turbine engine component and inspecting the component. A metallic flash coat is applied to at least a portion of the component. A ceramic top coat is then applied over predetermined portions of the component, including the portion to which the metallic flash coat was applied.
