Fluoride Ion Cleaning

Through the Fluoride Ion Cleaning (FIC) process, Walbar Peabody removes metallic oxides from metal alloys for nickel and cobalt based airfoil components, getting them ready for advanced braze repairs. This technology is capable of removing the oxides present on surfaces and within cracks.

Plating

Walbar Peabody specializes in single-phase platinum modified aluminide coatings for nickel-based alloys, with platinum applied via electrolytic plating and aluminizing by Chemical Vapor Deposition (CVD). Used on a number of programs, the site performs work and is OEM approved to comply with PW and GE coating specifications (CPW550 & CPW633, F50TF59 Class C, respectively).

Brazing

As a NADCAP, Gold Standard certified operation, Walbar Peabody’s advanced braze techniques focus on nickel and cobalt based alloys, with experts onsite specializing in the brazing of details and wide-gap braze repairs (complying with GEAE ADH, P&WC and limited Turbofix II specs). Our operation has a wide array of furnaces that enable broad brazing capabilities, such as vacuum and controlled atmosphere furnace brazing, all of which comply with AMS 2675 while also complying with additional customer/OEM specification as applicable (GE Aerospace CC01 per P9TF1; P10TF1; M50T1; ANSI/AWS C3.6; ANSI/AWS C3.7; S-405).

Advanced Stripping

As a NADCAP-certified operation (the gold standard),  Walbar Peabody’s chemical stripping operations comply with NADCAP AC7109/4 Rev B supplement and additional customer specifications as needed (IAW SPOP 301). These capabilities remove the surface protective coatings, such as diffused aluminide, enabling high quality weld or braze repairs on Nickle or Cobalt based alloys.

Heat Treating

As a NADCAP-certified operation (the gold standard), Walbar Peabody’s core operation is powered by a wide array of furnaces, enabling heat treatment for Brazing (nickel and cobalt-based alloys—complying with AMS2774, NADCAP AC7102/1, and customer specifications), vacuum heat treating for commercial repairs, and specific customer requirements, such as GEAE-U10, NADCAP AC7102/S and AC7102/1.

Nondestructive Testing

As a NADCAP-certified operation (the gold standard), Walbar Peabody’s Nondestructive Test (NDT) capabilities enable continuous validation of top-tier quality and reliability. With on-site Fluorescent Penetrant Inspection (PFI), Magnetic Particle Inspection (MPI), and Radiographic Inspection (X-Ray), Walbar Peabody complies with NADCAP – AC7114A Rev C, AC7114/1 Rev B, and OEM requirements (GEAE-S-U10, Pratt & Whitney S-U2).

Coatings

As a NADCAP-certified operation (the gold standard), Walbar Peabody performs a wide array of different coating operations, complying with a broad range of requirements: Chemical Vapor Deposition, complying with NADCAP AC7109/3 Rev B; Pack Process-Above Pack, complying with NADCAP AC7109/3; Pack Process-In Pack, complying with NADCAP AC7109/3; Slurry Process-Spray, complying with NADCAP AC7109/3. In addition to NADCAP standards, our coating processes comply with many OEM standards, such as: P&WC CPW-550, -537, -633; PWA77, PW SPOP 70-46-00 Plasma Spray, GEAE AP 70-49-00 Thermal Coatings, GE F50TF37 CL-B, GE F50TF68 CL-A & B, GE F50TF59 CL-C.

Metallurgical Analysis

To help ensure the highest level of quality and reliability, Walbar Peabody maintains an on-site metallurgical analysis laboratory where qualified technical experts perform tests and analyze hardware. While complying with NADCAP AC7109/5, this materials lab is MCL and CCL certified and is capable of performing the following analyses: coating composition, metallographic analysis, oxidation analysis, metallographic thickness testing, and the necessary specimen preparation to perform all tests.
