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.
