Liquid accelerated cold spray for copper deposition

The liquid accelerated cold spray (LACS) technology is an innovative process that uses a high-pressure liquid flow to accelerate metal and composite powders to very high velocities (above 500 m/s) so that, upon the impact on the substrate, they form a coating. Using a liquid instead of a gas as used in a traditional cold spray, makes it possible to spray particles with a larger size distribution owing to the high density of the liquid.

High Performance Cold Spray Process Development

PolyCSAM is a new industrial-scale cold spray additive manufacturing (CSAM) facility created by Polycontrols to address production and industrialization challenges. It serves as a demonstrator and an innovation/development platform. A recent strengths, weaknesses, opportunities, and threats (SWOT) analysis revealed that the supply chain is solid and diversified for all key components, with the exception of the cold spray (CS) gun itself.
