“…However, despite the prospects for using thin-film coatings as anti-corrosion protective materials, a number of problems remain, the solution of which will increase the service life of materials, as well as enhance their resistance to mechanical damage and high-temperature heating. One way to solve this problem is to use the methods of ion or radiation modification using low-energy ions or electron radiation [14][15][16]. This modification is based on the hypothesis that, during the interaction of incident charged particles (ions) with the crystal structure of thin films, energy transfer processes, accompanied by energy transformation of kinetic energy into thermal energy, lead to structural changes in film coatings and their hardening.…”

In recent years, much attention has been paid to research in the field of increasing resistance to external influences, including the corrosion resistance of steels and alloys exposed to aggressive environments or high temperatures. Interest in this area is due to the need to increase the service life of steel products, which will reduce the cost of most technological processes. The most promising methods for improving the strength characteristics, as well as resistance to corrosion degradation, are the application of various protective coatings to steel, among the variety of which one can single out nitride coatings that are highly resistant to corrosion and degradation caused by exposure to aggressive media. Also, one of the ways to increase resistance to external influences is the methods of changing the dislocation density in the near-surface layer, which make it possible to create a barrier layer for the penetration of oxygen and moisture through the protective coating. Based on the proposed corrosion protection methods, this paper considers the possibilities of combining the methods of applying nitride coatings and subsequent ionic modification in order to create a barrier protective layer against corrosion of 316L stainless steel. During the studies conducted, it was found that the magnetron deposition of a nitride coating (TiN) on the surface of stainlesssteel leads to a hardness growth by 10-13 %, and the subsequent ion modification, performed by the action of low-energy N2+ ions on the nitride coating with different irradiation fluence, leads to an increase in strength by 50-70 % compared to the initial value. As a result of corrosion tests to maintain the stability of strength properties, it was found that the most effective influence of ion irradiation is a fluence of 5×1013-1014 ion/cm 2 , leading not only to maximum hardening, but also to an increase in the corrosion potential, the alteration of which indicates a decrease in the degradation rate.

Transition metal nitrides have extensive applications, including magnetic storage devices, hardware resistance coatings, and low-temperature fuel cells. This study investigated the structural, electrical, and mechanical properties of thin zirconium nitride (ZrN) films by examining the effects of laser irradiation times. Thin ZrN films were deposited on glass substrates using pulsed DC magnetron sputtering and irradiated with a diode laser for 6 and 10 min. Characterization was performed using X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), nanoindentation, and four-point probe techniques. Extended laser irradiation times resulted in increased numbers of peaks on XRD analysis, indicating enhanced crystalline behavior of thin ZrN film. SEM analysis revealed surface voids, while HRTEM showed nanostructured ZrN with uniform plane orientation. The electrical properties of the thin ZrN film improved with extended laser irradiation, as demonstrated by a reduction in sheet resistance from 0.43 × 109 Ω to 0.04 × 109 Ω. Additionally, nanoindentation tests revealed an increase in hardness, rising from 8.91 GPa to 9.36 GPa.
