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. |

DETAILED DESCRIPTION We claim: 1.
A gas-dynamic spraying method for applying a coating to an article, the method comprising: introducing into a gas particles of a powder of at least one first material selected from the group consisting of a metal, alloy, polymer and mechanical mixture of a metal and an alloy, the particles having a particle size of from about 1 to 50 microns; forming the gas and particles into a supersonic jet having a temperature sufficiently low to prevent thermal softening of the first material and a velocity of from about 300 to about 1,200 m/sec.
; and directing the jet against an article of a second material selected from the group consisting of a metal, alloy and dielectric, thereby coating the article with the particles.
2.
The method of claim 1, wherein the gas is selected from the group consisting of air, helium and a mixture of air and helium.
3.
The method of claim 1, wherein the temperature of the jet is room temperature, the gas is air, the first material is aluminum and zinc and a flow rate of the particles in the jet is at least 0.
05 g/sec.

The method of claim 1, wherein forming the jet comprises forming the jet with a cross section having one maximum dimension bigger than a perpendicular maximum dimension.
Description:
The present invention relates to metallurgy, more specifically, a method of and an apparatus for applying a coating.
BACKGROUND ART Protection of structures, equipment, machines, and mechanisms made of ferrous metals from corrosion and effect exerted by aggressive media, an improvement of specifications of materials, including obtaining materials with prescribed properties, and development of resource-saving processing technologies are important scientific, technical and practical problems.
These problems can be solved by various methods, including applying powder coatings with widely usable gas flame-spray, electric arc, detonation and plasma methods
