Abstract
The feasibility of updating the series-produced air-plasma cutting plasmatrons for their application in plasma spraying of powdered materials is shown. Method of optimizing of geometric sizes of a channel of nozzle and anode to achieve optimum values of the material utilization factor is given.
Keywords: plasmatron, gas-air plasma, thermal spraying
