Cold Spray



Cold spray is a solid-state spray process that deposits metal powder with temperatures below the material melting point through the use of a supersonic nozzle and pressurized/heated inert gas

. Concurrent Technologies Corporation uses high pressure cold spray for the application of metals, metal alloys and metal blends to create new parts, repair existing parts, and/or enhance base material properties (e.g., improved corrosion or wear protection).

Benefits of Cold Spray
  • Low heat input with no “heat-affected zone”
  • Work-hardened and near-wrought properties can be achieved
  • No limit on deposition thickness
  • High deposit efficiency typically > 80%
  • Deposition density > 99%
  • Powder microstructure and properties are preserved
  • No oxide formation, alloy decomposition, combustion product entrapment
  • A diversity of materials that can be applied from aluminum to refractory metals

Specialized Equipment
Concurrent Technologies Corporation utilizes a VRC Metal Systems Gen III Max system, which uses three 15kW heaters mounted within a single mobile unit.

The Gen III Max only takes up a small three-foot by five-foot area and is on wheels, enabling easy mobility for production, repair or in-the-field applications. It can be manually or robotically operated, providing a versatile feature that makes it the system of choice for many repair and obsolescence applications.

Parts Repairs
Cold spray is being used industry-wide to repair expensive and/or hard-to-acquire components on military aircraft, vehicles, and even submarines, which would otherwise be scrapped. Cold spray provides a cost effective means to reset the part and address long lead times or part obsolescence.

The high pressure cold spray process utilizes metal-based powders, which are accelerated at supersonic velocities onto the surface of a part that has been worn or damaged. Upon impact, the powder is consolidated into a dense solid material only requiring finish machining to restore the part back to its original dimensions. The resulting deposition can range from ~0.01 inch up to any desirable thickness.
