Cold spray is a relativity new technology for deposition of powder coatings . In this technology heated and compressed gas used for accelerating of particles to a high velocities (500-1500 m/sec) at relativity small temperatures.
Deposition of particles on substrate occures without melting as the result of plastic deformation. Cold spray technology has a great innovation potential
