Cold Spray is a process of applying coatings by exposing a metallic or dielectric substrate to a high velocity (300 to 1200 m/s) jet of small (1 to 50 ?m) particles accelerated by a supersonic jet of compressed gas. This process is based on the selection of the combination of particle temperature, velocity, and size that allows spraying at the lowest temperature possible. In the Cold Spray process, powder particles are accelerated by the supersonic gas jet at a temperature that is always lower than the melting point of the material, resulting in 606 $aSpraying 606 $aMetals$xFinishing 606 $aDielectrics$xFinishing 606 $aGas dynamics 615 0$aSpraying. 615 0$aMetals$xFinishing. 615 0$aDielectrics$xFinishing. 615 0$aGas dynamics. 676 $a671.73 701 $aPapyrin$b Anatolii$01823611 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911006694803321 996 $aCold spray technology$94390368 997 $aUNINA
