Application of Cold Spray Coatings for Repair of Aerospace Parts

There are currently no practical-economical repair methods for many aerospace parts made

of aluminum/titanium. The Cold Spray technology produces metal coatings by accelerating

metal powders onto the substrate to be coated using high velocity jet at supersonic speeds.

Upon impact the particles plastically deform and produce a dense coating. Metals such as

aluminum/titanium can be applied by this process without damaging the parts to be coated.

As such, it is believed that Cold Spray can be used to restore/repair damaged

aluminum/titanium aerospace coatings/parts as well as other parts. Its successful

implementation as a restoration/repair technology will result in major cost savings and reduce

schedule time and thus will allow the Canadian technologies developed and commercialized

by Centerline to be adopted by aerospace companies such as Boeing and generate

considerable revenues from selling the equipment, parts and know-how. The interns will

perform intensive research and development activities using the Cold Spray technology in

order to develop and complete the feasibility and qualification-certification testing….
