ARL Center for Cold Spray

Applications

The cold spray process is applicable to corrosion-resistant coatings (zinc and aluminum), dimensional restoration and repair (nickel, stainless steel, titanium and aluminum), wear-resistant coatings (chromium carbide/nickel chromium, tungsten carbide/cobalt, and tungsten copper), electromagnetic interference shielding of components and structures, and field repair of components and systems. Military standard MIL-STD-3021 was issued to develop the manufacturing process controls for cold spray operation.

The following figures show some of the many applications for cold spray. They include protective coatings, structural and non-structural repairs and additive manufacturing.
