“…The most widely used are methods based on plasma of vacuum-arc charges [3,4] or of a discharge glowing in gas [5]; plasma generated when a material is evaporated under powerful energy flows (laser emission, electron or ion beams) and plasma is formed in a facility generating Compressive Plasma Flows (CPF) ), velocity of plasma flow (10 3 -10 5 m/s), temperature (from 2 to 5 eV), duration of exposure from 80 to 200 µs, allowing to settle a wide range of scientific and practical tasks of the exposure of various materials to high-intensity energy flows [8,9].…”

Abstract. The prosperity of plasma technologies stimulates making of a facility generating compressive plasma flows at the South Ural State University. The facility is a compactgeometry magnetoplasma compressor with the following parameters: stored energy up to 15 kJ, voltage of a bank from 3 to 5 kV; nitrogen, air, and other gases can serve as its operating gas. The investigation of parameters of the facility showed the following parameters of compressive plasma flows: impulse duration of up to 120 µs, discharge current of 50-120 kA, speed of plasma flow of 15-30 km/s. By contrast to the available facilities, the parameters of the developed facility can be adjusted in a wide range of voltage from 2 kV to 10 kV, its design permits generating CPF in horizontal and vertical positions.

“…As a rule, the available publications mainly address particular technological tasks [9,10] and do not deeply analyse physical nature of the obtained results. Thus, with a bulk of experimental data on the CPF interaction with a solid body, there appears an urgent need in systematic experimental and theoretical study of the problem.…”
