Abstract
The influence of the compression plasma flow generated by the magnetoplasma compressor of the edge type on the carbon steel surface in different modes is investigated. The half-period of the oscillations was T / 2 = 6 μs. The voltage on a capacitor bank with a capacitance C = 18 μF was varied by U = 10-20 kV.The impulse treatment was carried out in a residual air atmosphere at a pressure p = 133 Pa at a fixed distance to the sample d = 44 mm. The behavior of the plasma stream was visualized by the shadow method of Tepler and the calculated velocity was ϑ = 104 m / s. The hardness of the surface was measured by the Oliver-Farr method, and an increase in hardness was recorded, including an anomalous hardening σ = 16 GPa.
