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. The technology has the potential to reduce considerably the spraying costs (as compared to the current gas accelerated cold spray processes) and to deposit coatings on internal surfaces or surfaces difficult to access.
