The cold spray method for metal deposition provides non-porous, highly adhering coatings to many lightweight aircraft materials. Metal deposition by cold spray does not subject the substrate material to high, damaging temperatures. This technique can be applied to the repair of relatively deep gouges, to corrosion protection, or both. Several examples of cold spray repair to aircraft surfaces will be described, including repairs to aluminum, alclad, magnesium and titanium. The use of both stationary and portable cold spray systems for aircraft material repair will be described and the relative advantages of each will be discussed.
