FIELD: for producing powders of metals and alloys and for applying coatings by means of gas-phase process.
SUBSTANCE: evaporator includes heater, cylindrical cells forming reservoir for melt metal, jets, ducts for inlet of melt metal and for outlet of its vapors, by-passing distributing branch pipes. According to invention heater is assembled of hollow cylindrical members mutually joined through electrically conducting couplings. Each cylindrical member of heater along its height serves as wall of cylindrical cell limiting size of cell in radial direction. On end of disc-like covers of each cylindrical cell (except upper lid along axis of which plug with duct melt metal inlet is mounted) jets are arranged coaxially relative to axis of evaporator. Plug and jet of upper cell and each next jets of cells restrict annular cone-like cavity inclined towards lower jet. Cavities and axial openings of jets form duct for outlet of vapor of melt metal.
EFFECT: reduced consumption of material, electric energy, improved operational reliability of structure.
