  • Gas-dynamic spraying method for applying a coating
    Patent number: 5302414
    Abstract: A cold gas-dynamic spraying method for applying a coating to an article introduces into a gas particles of a powder of a metal, alloy, polymer or mechanical mixture of a metal and an alloy, the particles having a particle size of from about 1 to about 50 microns. The gas and particles are formed into a supersonic jet having a temperature considerably below a fusing temperature of the powder material and a velocity of from about 300 to about 1,200 m/sec. The jet is directed against an article of a metal, alloy or dielectric, thereby coating the article with the particles.
