Maintenance, repair, and overhaul (MRO) are crucial to the aerospace industry—and as an MRO facility, Walbar Peabody fills that role with our deep, tenured expertise. Repairing hot section engine components is critical to saving customers time and money, ensuring the longevity of their aircraft, and keeping them up in the air. 

But what does that mean, exactly? How do we do what we do? 

Walbar Peabody fully restores gas turbine airfoils and structural components for commercial, regional, and business aircraft worldwide.

We also specialize in original equipment diffusion coating and vacuum brazing for engine manufacturers and sub-tier suppliers. We use proprietary coatings developed in partnership with engine OEMs to support both Repair (Part 145) and OEM product families. 

Our commitment to speed, safety, and quality is at the center of everything we do. Learn more about our core competencies and highly competitive turnaround times, which are both the result of our streamlined processes.

Core Competencies

Walbar Peabody excels in many foundational repair and manufacturing techniques, which are essential to restoring and enhancing the performance of various aerospace components. All of our engineers are trained in and always brushing up on these skills, which include: 

 

  • EDM Hole Drilling: Uses electrical discharge machining (EDM) to precisely drill cooling holes in turbine components, ensuring optimal performance and longevity
  • Welding: High-precision welding techniques to restore or reinforce critical aerospace components, maintaining structural integrity
  • Advanced Braze Repairs: Uses specialized brazing techniques to bond and restore damaged or worn metal components
  • Brush Nickel Plating: A selective plating method that applies nickel coatings to enhance wear resistance and corrosion protection
  • Chemical Vapor Deposition: A process that forms protective coatings on metal surfaces to improve durability and heat resistance
  • Diffusion Coating: Enhances surface properties by diffusing protective elements into the material, increasing oxidation and corrosion resistance
  • Electron Beam Welding: A high-energy welding process that fuses metal parts with extreme precision and minimal distortion
  • Machining: Precision cutting, grinding, and shaping of aerospace components to meet exact specifications
  • Pack Process Coatings: A method of applying protective coatings to components through a diffusion-based process in a controlled environment
  • Plasma Spray: Uses high-temperature plasma to apply protective ceramic or metallic coatings to turbine components
  • Platinum Aluminide Coatings: A specialized coating that enhances oxidation resistance in high-temperature environments
  • Scanning Electron Microscopy: Advanced imaging technology used to inspect and analyze material surfaces at a microscopic level
  • Shot Peening: A surface treatment process that enhances fatigue strength and stress resistance by bombarding components with small spherical media

Turnaround Times: Striving to Exceed Expectations

Time on the ground costs money, so we’re constantly focused on process improvement and boosting efficiencies to deliver optimal results for our customers.

With a tenured team equipped with broad backgrounds, we have learned from past challenges and gaps. By adhering to strict industry and manufacturer requirements and doing things right the first time, we have some of the best turnaround times (TATs) in the industry. These include: 

  • Shrouds: 4 days
  • Cases/Seals: 5.5 days
  • Gears/Carriers: 16 days
  • OEM Blades: 16.5 days
  • CF6 LPT Nozzles: 22 days
  • Repair Blades: 16.5 days
  • Platinum-Coated Blades: 28 days

All other products are completed ASAP according to the customer’s timeline and our capabilities.
