How It Works


    For over a decade, we have worked closely with the US Army Research Lab, which is recognized as the DoD’s expert in Cold Spray. Having extensive experience using Cold Spray to repair commercial & military components, we’ve successfully developed repairs for corroded or damaged areas on hard-to-repair parts including: transmission gearboxes, sump housings, engine components, landing gear components, & more. 


    Our comprehensive cold spray repair services provide manufacturers and end users an economical repair solution for corroded and damaged parts. Using an advanced additive manufacturing process for metal surfaces that does not induce thermal stresses into the parent or deposited material, cold sprays unique properties are compatible with many aerospace materials. The low or high pressure system options allow application of lighter materials or enhanced capabilities to provide dramatic improvements in process characteristics and performance.

T6 Wheel

We developed Cold Spray repairs for both the Main Landing Gear and Nose Wheel assemblies for the T-6 aircraft.

T-700 Engine

We established and qualified a Cold Spray repair for the T700 Engine Front Frame. The contact surface between the inlet guide vane spindle and the front frame housing is prone to corrosion and wear.

More Information

Does Moog provide approval of a given repair?

Since repair approval requirements can vary widely, Moog relies on the customer to advise on the approval requirements. Approvals can involve the customer, the FAA, the OEM, and/or various military organizations (for military applications). For commercial repairs, Moog can obtain FAA DER approval of repairs developed by Moog, or utilize applicable customer held DER repairs.

What is the lead time for repair of follow-on units?

Once the repair has been established and approved by the customer, lead time for follow on components is about 30 days after receipt of the components. Complex repairs with external process support may require additional time.

Does Moog sell cold spray equipment?

We do not sell equipment. We only provide cold spray repair services using a variety of spray systems, depending on each particular repair application.

Are turn-key repairs provided (i.e. pre-machine, spray, post-machine, etc.)?

We have the capability to provide cold spray repair only, or a complete “turn-key” repair solution with complete documentation of the repair as required. 

How do you verify that a repair meets the needed requirements?

When we cold spray a part, we always prepare a set of coupons which we also spray and test to verify properties. The data we gather from the coupons provides the assurance and correlation that our cold spray application on the part is acceptable.

What is the typical time required to evaluate and spray a First Article unit?

The typical lead time for engineering evaluation of a component, development of the repair procedure, and spraying a First Article unit is typically 60 to 90 days after receipt of the component. This lead time may be shorter or longer depending on the amount of technical information we receive from the customer, such as drawings or repair documents. Repair approval requirements may incur additional time.

How is the appropriate metal to be used for a given repair determined?

Once we know the type substrate the part is made of, as well as the material hardness, our engineers and metallurgists develop a proposed repair, to include identifying the metal powder which most closely matches the substrate properties and/or yields the most desirable repair characteristics.

What metals do you work with?

Aluminum, Brass, Bronze, Copper, CRC-NiCr, Inconel, Monel, Nickel, Niobium, Silver, Steel, Stainless Steel, Tantalum, Tin,Titanium, Zinc, Zirconium
