Spraying plasmatron coatings with powder supply to plasma flow

The efficiency of using plasma energy when applying coatings is largely determined by the design of the plasmotron. The main difference of the developed plasmotron PM-1 is the supply of transporting gas with powder to the plaza flow, which allows for a more efficient and even heating of the sprayed material. This paper presents the results of measuring the efficiency of the use of material, which is an important and indicative characteristic of plasmotrons, showing their economy and productivity, calculated the cost of electricity and conducted studies of sprayed samples for thermal shock.
