Closure of Cooling Holes with a Filling Agent

A method for filling cooling holes in a component of a gas turbine engine, the component having an outer surface and an inner surface and a plurality of first cooling holes, the plurality of first cooling holes extending between the outer surface and the inner surface of the component, the method comprising the steps of:

• exposing the outer surface of the component;
• filling the plurality of first cooling holes with a polyimide;
• curing the polyimide to block the plurality of first cooling holes;
• and
• applying a thermal bather coating over the outer surface of the component.

A component of a gas turbine engine comprising:

• a plurality of first cooling holes extending between an outer surface and an inner surface of the component, the plurality of first cooling holes being filled with a polyimide, the polyimide being cured to solid form to block cooling fluid flow through the plurality of first cooling holes;
• a thermal barrier coating over the outer surface of the component;
• and
• a plurality of second cooling holes, the plurality of second cooling holes extending between the thermal barrier coating and the inner surface and allowing cooling fluid to pass therethrough.
