“…The formation of texture in coatings deposited from energy ion fluxes is considered in conjunction with stresses and is associated with the possibility of minimizing the free energy of the system consisting of strain energy and surface energy [54,55]. The texture axis varies depending on the ion energy, deposition temperature, the angle of the substrate relative to the flow of deposited particles, etc.…”

“…The texture axis varies depending on the ion energy, deposition temperature, the angle of the substrate relative to the flow of deposited particles, etc. [55,56]. The change in the predominant orientation in h-VN coatings from (00l) to (h00) is most likely due to a decrease in the substrate rotation speed from 30 [33] to 9 rpm and the substrate-cathode distance of 400 mm.…”

The V-O-N coating set was produced at different relative oxygen concentrations of O2(x) = O2/(N2 +O2) using cathodic arc evaporation. The aim of the research was to determine the effect of oxygen on coating properties. The coatings’ composition and structural properties (X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX)) and mechanical properties—hardness, adhesion, and wear resistance (nano-indenter, scratch tester, ball-on-disc tester)—were extensively investigated. EDX and XRD analyses indicate that in coatings formed with a relative oxygen concentration in the range of 20–30%, the oxygen concentration in the coating increases dramatically from approximately 16 at.%. to 63 at.%, and the nitrogen concentration drops from about 34 at.% up to 3 at.%. This may indicate greater activity of oxygen compared to nitrogen in forming compounds with vanadium. The occurrence of the V5O9 phase belonging to the Magnéli phases was observed. Microscopic observations indicate that the number of surface defects increases with the oxygen concentration in the coating. The opposite effect is characterized by mechanical properties—hardness, adhesion, and wear resistance decrease with increasing oxygen concentration in the coating.

“…MAX phases of Ti-Al-C, Cr-Al-C, V-Al-C, and Ti-Al-N systems with different crystal phase orientations: (110), (103) (100), (001) have been synthesized in polycrystalline layers by different PVD deposition methods [6,30,38,40,[56][57][58]. It is well known that the formation of texture in coatings deposited by energy ion fluxes is considered in the context of stresses and is related to the attempt to minimize the free energy of the system, which consists of strain energy and surface energy [59,60]. For MAX phases (space group P6 3 /mmc), the (0001) basal plane is the most stable orientation due to the lowest surface energy [61].…”

The unique hybrid properties of ceramics and metals due to their special nanolayer structure make MAX phases an attractive material for working in harsh environments. Successes in the development of PVD processes for the synthesis of nanocrystalline coatings of MAX phases at low temperatures on technologically important substrates open up significant prospects for their application. This part of the review is devoted to the properties of MAX phases that make them useful for creating multifunctional coatings to protect the surface of materials operating under difficult conditions of high temperature, corrosion, and radiation. The influence of PVD deposition parameters on the structure of MAX phase coatings is analyzed. The peculiarities of the mechanical and tribological properties of the coatings, their resistance to erosion, corrosion, and radiation, and their ability to self-repair damage at high temperatures are discussed. Prospects for the use of MAX phase PVD coatings in various industries and ways to improve their protective properties are considered.

“…The synthesis of TiN coatings on a substrate takes place under conditions of intense ion bombardment of the deposited coating surface by metal and gas ions, so the substrate potential has a significant effect on its temperature and on the elemental and phase composition of the coating. The substrate potential and its temperature determine the level of internal stresses in the coating [32], which can reach values of up to 8 GPa. Internal stresses above a certain critical value in the substrate-coating system can significantly reduce the cavitation resistance of the material.…”

This review presents an examination of various studies investigating the impact of deposition process conditions and structural characteristics of TiN-based vacuum-arc coatings on their ability to withstand cavitation erosion in water. The structural and phase composition of TiN coatings is influenced by two key technological parameters: the nitrogen pressure in the vacuum chamber and the substrate bias potential. However, it has been observed that vacuum-arc alloy coatings such as TiSiN and TiAlYN exhibit notably lower resistance to cavitation erosion. Additionally, research on multilayer Ti-TiN coatings with varying numbers and thickness ratios of layers has not shown an improvement in resistance to cavitation wear when compared to single-layer coatings deposited under optimal conditions. On the other hand, single-phase stoichiometric TiN coatings deposited at a higher nitrogen pressure of 2 Pa and a bias potential of up to -300 V have demonstrated remarkable resistance to cavitation wear. These coatings could be effectively utilized to protect the titanium alloy Ti-6Al-4V against cavitation damage.
