ABSTRACT:
The invention solves the problem of spraying metallic coatings on difficult-accessible surfaces, especially on internal surfaces of long glass pipes having a small diameter which can be applied as electrodes in ozone generators. The method of spraying metallic coatings according to the invention consisting in melting metal in the electric arc and atomizing it by a stream of compressed gas is characterized by that molten metal is applied on the surface to be coated by means of a closed system of three-stream atomization, which comprises the following streams of compressed gas: a stream directed along wires being melted, a side stream and an opposite blowing-away stream, whereas the head, apart from correspondingly directed nozzles for compressed gas, has also a special connection of wires being melted, constituting electrodes, to a source of current, in a form of flexibly mounted rings inside which said wires are fitted in a manner enabling their continuous shift.
