“…A comparatively short treatment time (a few tens of minutes -a few hours) is the main advantage of these methods in comparison with convenient nitriding. The use of techniques based on the direct interaction of high temperature plasma with a material allows to decrease even this period [10][11][12]. Direct dense plasma flows with small divergence and high energy (up to 30 J/cm 2 ) can modify a layer with thickness of tens of micrometers in an extremely short time < 1 second.…”

The influence of the nitrogen compression plasma flow impact on the phase and element composition, tribological properties of AISI M2 and AISI T1 high-speed steels was investigated in this work. The bank capacitor initial voltage, the number of pulses and nitrogen pressure in the vacuum chamber varied during experiments providing the change of energy deposited in the surface layer within the limits of 5-13 J/cm 2 per pulse. It was found that treatment resulted in carbides partial dissolution and austenite formation in the surface layer. The modified layer thickness amounted to 24 μm while the nitrogen penetration depth did not exceed 400 nm.Treatment by the compression plasma flow mainly led to the decrease of hardness and the friction coefficient of high-speed steels.

“…Although, pulsed plasma sources have been available for quite some time, their application to material modification has been seen only recently. Garkusha [95][96][97] and their group at the National Science Center 'Kharkiv Institute of Physics and Technology' (NSC KIPT) employed ultra-short (10 −6 s) energetic plasma pulses to tailor the material surface properties. They reported a four times increase in surface hardness even for previously quenched steels, and a four to 10 times improvement in wear resistance and enhancement of corrosion and erosion characteristics.…”

Several advances in materials research have been made due to the wide array of tools currently available for the processing of materials: plasmas, electron beams, ion beams and lasers. The area of material science is fortunate to have seen the development of these tools over the years, be it for new bulk materials, coatings or for surface modification. Several applications have benefited and many more will in the future as the properties of the materials are altered on a micro/nanoscale. Currently, several techniques exist to modify the physical, chemical and biological properties of the material surface; however, this review limits itself to surface modification applications using the rapid thermal processing (RTP) technique. First, a brief overview of the existing surface modification methods using the principles of RTP is reviewed, and then a novel method to create micro/nanostructures on the surface using pulsed plasma exposure of materials is presented.

The paper is devoted to experimental measurements and analysis of parameters of the plasma streams generated by magnetoplasma compressor (MPC) upgraded with an external axial magnetic field. Influence of the external axial magnetic field of 0.24 T on helium plasma streams (P=2 Torr) has been studied. The measurements of average electron density distributions were performedboth with and without an external axial B-field. Distributions of plasma electron density Ne (L) were measured with spectroscopy in the plasma stream and in the compression zone using Stark broadening of He I and He II spectral lines. Plasma-surface interaction processes were also analyzed.
