High-Tech Repair Solutions: Enabling Lower Total Cost of Ownership

Honeywell continues to grow our portfolio of highly specialized techniques for aircraft component repair. These advanced repairs optimize customer value through extended product life, reduced scrapping of expensive components, and lower total cost of ownership.

Our commitment to reducing maintenance spend is demonstrated by our development and delivery of cost-effective advanced repair processes. Our technology repair roadmap guides our repair development efforts to meet our customers' current and future repair requirements. With more than 230 engineers, our Global Repair and Overhaul Engineering team works to create new repairs and extended work scopes for Honeywell products. This team explores new technologies and innovative repair procedures that extend product lifespan and increase repair yield, enabling a like-new condition.

Our engineering expertise enables the ability to develop specific repairs with Original Equipment Manufacturer (OEM) reliability on Honeywell components. Our network of Global Repair Centers of Excellence supports our advanced repair techniques and presents the highest levels of engineering support and customer service no matter the repair. Through our Honeywell Operating System, Six Sigma, and Lean processes, we deliver responsive turnaround times and on-time delivery performance.

These advanced repair solutions have been proven on our industry-leading Auxiliary Power Units, TFE731, and TPE331 engine platforms, and are now being introduced to our HTF7000 platforms.

Honeywell advanced repairs include:

Adaptive Machining

Honeywell's advancements in adaptive machining systems provide comprehensive solutions for repairing and refurbishing variable-geometry 3-D components. Using the latest in 5-axis machine tools, each repair is optimized to its unique contour with minimal effect on the parent material. Honeywell uses this technology to repair impellers, blisks, and turbine rotors and blades, reducing the total cost of ownership for our customers. 

Laser Welding, Brazing, and Thermal Processing

To deliver innovative repairs for the latest engine components, air cycle machines, valves, heat exchangers, and fuel control parts, while extending our work scopes for existing parts and components we push the envelope of advanced welding, heat treating, thermal sizing and high-technology brazing restoration processes. We work with new adaptive and automated laser welding technologies and brazing techniques to create high-precision repairs that are cost-effective, even for those components with complex part geometries and one-piece castings.

• 3-D Adaptive Laser Powder Fusion Welding

• Hand-held Laser System Welding

• Laser Welding, Cutting, and Drilling

• Vacuum Furnace Brazing and Heat Treatment

• Fluoride Ion Cleaning

• Electron Beam Welding

JetFix® Gas Turbine Repair Services

Honeywell's JetFix® repair services can repair severe fatigue cracks and metal erosion due to harsh engine operating environments. We use a specially formulated alloy mixture to match the original part strength. JetFix® repair service is used on turbine airfoils and includes removing the original coatings, fluoride Ion cleaning of cracks, application of the JetFix® special alloy, vacuum diffusion of the alloy, blending, recoating, and final airflow check before shipment back to the customer

Surface Treatment and Coatings

Our surface treatments and specialty coatings prevent corrosion and erosion while improving the high-temperature capability of engine parts and components. Honeywell is developing new treatment technologies and applications, including:

• Water Jet, Abrasive, and Chemical Stripping

• Thermal Spray Coatings

• CVD Aluminide Coatings

• CVD Platinum Aluminide Coatings

• EB-PVD Ceramics

• EB-PVD Metallic Coatings
