摘要：

The interaction of a dense compressive nitrogen plasma flow with carbon steel specimens has been investigated. The flows were generated by a magnetoplasma compressor, in which the acceleration of a plasma is accompanied by its compression due to interaction between the longitudinal constituent of electric current and the intrinsic azimuth magnetic field. As a result, a layered structure with a total depth of up to 25 mum is formed at a specimen surface. Investigations of a surface structure and its phase composition were carried out using X-ray diffraction, Mossbauer conversion electronic spectroscopy, and optical microscopy methods, along with the studies of mechanical properties.
