The theoretical analysis of the interaction of the flame spray of molten wire at the site of metal sprayed is performed. A simplified method for describing the decision to reduce the diameter of the melt at the end of the spray wire has been proposed. The mechanism of separation of drops of molten metal sprayed from a wire upon application of ultrasonic vibrations was considered. It is shown that with increasing intensity ultrasound increases the efficiency of dispersing droplets sprayed wire.
