Abstract
A method for in-frame repairing of a thermal barrier coating () on a gas turbine component includes cleaning a desired surface portion () of the component without removing the component from the gas turbine. The method also includes roughening the surface portion in-frame, applying a bond coat () to the surface portion in-frame, and applying a ceramic topcoat () to the bond coat, in-frame. A system () for cleaning the surface portion in-frame includes an abrasive media () having a state change characteristic occurring at a temperature lower than an operating temperature of the gas turbine so that the abrasive media changes from a solid state to another state allowing the media to exit the gas turbine during operation. The system also includes an abrasive media sprayer () to direct a spray of the abrasive media at the desired surface portion.
