Pulse–periodic source of high-energy plasma flows at air for thermal technology applications

Principles of generation of high-energy pulse plasma flows and design of a hybrid electromagnetic plasmadynamic system-pulsed–periodic plasmatron are described. This electromagnetic plasmadynamic system operates at standard atmospheric pressure with high frequency. The plasma flow velocity reaches 3–5 ∙ 103 m/s with a temperature up to 15 ∙ 103 K. The results of investigations of pulsed–periodic plasmatron operations and carbon steel (0, 45% C) surface layer modification are presented.
