Method for repairing a gas turbine engine component

A gas turbine engine component repaired according to a process comprising the steps of:

• providing at least one gas turbine engine component comprising at least one portion comprising at least one aperture including a first size and corrosion;
• removing the corrosion from the at least one aperture to form at least one aperture free of corrosion and comprising a second size;
• treating the at least one aperture free of corrosion and comprising a second size to form at least one treated aperture free of corrosion;
• disposing an amount of at least one anti-corrosion agent on the at least one treated aperture free of corrosion to form at least one anti-corrosion agent-coated treated aperture free of corrosion, the at least one anti-corrosion agent comprising any one or more of the following:
• rubber, fluoroelastomer, and combinations thereof;
• and
• removing at least a portion of the anti-corrosion agent from the at least one anti-corrosion agent-coated treated aperture free of corrosion to form at least one aperture free of corrosion comprising the first size and a residual amount of the anti-corrosion agent.

A gas turbine engine comprising:

• at least one low-pressure compressor assembly comprising at least one vane, the at least one vane repaired according to a method comprising the steps of:
• providing at least one vane comprising a vane base housing having at least one portion comprising at least one attachment bolt aperture including a first size and corrosion;
• removing the corrosion from the at least one attachment bolt aperture to form at least one portion free of corrosion and comprising a second size;
• treating the at least one attachment bolt aperture free of corrosion and comprising a second size to form at least one treated attachment bolt aperture free of corrosion;
• disposing an amount of at least one anti-corrosion agent on the at least one treated attachment bolt aperture free of corrosion to form at least one anti-corrosion agent-coated treated attachment bolt aperture free of corrosion, the at least one anti-corrosion agent comprising any one or more of the following:
• rubber, fluoroelastomer, and combinations thereof;
• and
• removing at least a portion of the anti-corrosion agent from the at least one anti-corrosion agent-coated treated attachment bolt aperture free of corrosion to form at least one attachment bolt aperture free of corrosion comprising the first size and a residual amount of the anti-corrosion agent.
