摘要

Method of applying coating to superfu00eccies, use of a powder of a material, a layer of spraying cold coated object and the use of a coating of refractory metal.The present invention relates to a method for application of coatings to surfaces, in which a flow of gas in a gas mixture powder with powder of a material selected from the group consisting of niobium, tantalum, tungsten, molybdenum, titanium, zirconium, or mixtures of P. At least two of them, or their alloys with at least two of them, or with other metals.The powder having a particle size of 0.5 to 150 PM, in which a supersonic speed is imparted to the gas flow and the jet in supersonic speed is directed to the surface of an object. The coatings prepared are used, for example, as coatings for corrosion protection.
