Cold Spray Process
Vivid is proud to offer cold spray, an innovative coating application. Cold Spray is a groundbreaking development in the field of high kinetic energy coating procedures. The unique, innovative process involves lower temperatures and an extremely high velocity Cold Spray, which provides many advantages to the substrate of the material being coated.
The cold spray process uses energy from high pressure, compressed gas to propel fine powder particles at extremely high velocities. The Cold Spray consumable gas, which is typically helium, is fed through a heating unit to a specially designed nozzle. Simultaneously, during the Cold Spray process, a similar compressed gas is feeding the powder into the high velocity gas jet. Through this Cold Spray process the particles are accelerated to a specific velocity and temperature where on impact with the substrate they bond to form a coating. The bulk of the reaction on impact has the Cold Spray coating consistently remaining in a solid state. The Cold Spray coating process has limited oxidation, which has many end-user benefits.
