Special Issue Information
Dear Colleagues,
The plasma-based surface modification technologies developed in recent years allow us to improve operational characteristics of various parts made of any materials, being it metals, dielectrics or composites. The high efficiency of this approach may be explained by the fact that under the diversified operating conditions of the parts, in all cases, the most loaded is the surface layer. Different technological techniques, such as surface layer hardening and alloying (chemical-heat treatment, implantation), coating deposition (physical and chemical methods), a combination of both methods, and other solutions use low-pressure gas discharges for the plasma generation. These are the glow discharge, vacuum arc, radio frequency (RF) and microwave discharges, as well as discharges with thermionic cathodes.
The efficiency of both the surface layer hardening and coating deposition can be appreciably improved with the use of broad beams of accelerated ions or fast neutral atoms. The ions are extracted from the gas discharge plasma by accelerating electrodes, for example, grids. The fast atoms appear due to charge exchange collisions of accelerated ions with gas molecules or due to collisions with a metal surface at a grazing incidence and recombination with electrons pulled out from the metal surface. It should be additionally emphasized that the beam-assisted deposition of coatings can be carried out using a beam of fast gas atoms obtained in the same plasma of the discharge generating metal vapor for the coating deposition; for instance, magnetron discharge or vacuum arc.
The aim of this Special Issue is to provide a review of the current state of the research and developments in the field of plasma coatings and surface modification technologies that can ensure a substantial increase in the useful life and reliability of the parts and other important manufacturing factors.
Some of the topics of particular interest to the Special Issue are as follows:
- Filling voluminous vacuum chambers with a homogeneous plasma at the gas pressure not exceeding 0.01 Pa for the plasma immersion ion implantation into the surface of conductive parts;
- Broad beam sources of high-energy neutral atoms for the modification of the dielectric part surface;
- Nitriding of the parts in plasma produced by a broad ion beam injected into a vacuum chamber;
- High-rate deposition of dielectric coatings using magnetron-sputtering systems with liquid targets;
- High-rate low-temperature deposition of thick aluminum oxide and aluminum nitride coatings by anodic evaporation of aluminum in the arc discharge;
- Development of pulsed detonation technology for modification of material properties and high-rate coating deposition using plasma jets;
- Coating deposition using the cathodic arc evaporation at a number and sizes of emitted from the cathode spots droplets reduced due to supply of the reactive gas into the vacuum chamber through the cathode;
- Influence of the plasma coatings on the stress–strain state and wear of the parts subjected to various heat and force loads;
- Original technological equipment and setups for plasma coatings and surface hardening of the parts, including low-temperature techniques.
