The efficiency of using plasma energy when applying coatings is largely determined by the design of a plasma-tron. The main difference of the developed plasmatron PM-1 is the supply of transporting gas with powder to the plaza flow, which allows us to ensure more efficient and uniform heating of the material being sprayed. This paper presents the results of measuring a material usage factor (MUF), which is an important and indicative characteristic of plasmatrons, showing their economy and productivity. The authors calculated the cost of electricity and con-ducted studies of the sprayed samples for thermal shock.
Keywords: plasmatron, technical regime, heat-protective coating, samples, spraying, plasma jet, material usage factor.
