“…They can be used to solve the fundamental and applied problems, such as fabricating coatings, studying their structure and properties, or using the products covered with these coatings in practice [1][2][3][4][5]. The nitrides and carbides from HEAs significantly improve the characteristics of materials: radiation, wear, and corrosion resistance.…”

a b s t r a c tThe multicomponent nitride coatings from TiZrNbAlYCr high entropy alloy (HEA) were fabricated using the vacuum-arc method. The effect of nitrogen pressure on the crystallite size, elemental and phase composition of (TiZrNbAlYCr)N coatings was investigated. A bias voltage applied to the substrate during the deposition process was À200 V. The partial nitrogen pressure was 0.05 Pa, 0.27 Pa, and 0.5 Pa. Bodycentered cubic (BCC) lattice with crystallites of 15 nm in size was formed at the lowest pressure. An increase in the pressure led to the formation of the two-phase structure: BCC phase with crystallite size of 15 nm and face-centered cubic (FCC) phase with crystallite size of about 3.5 nm. The same two-phase state was found in coatings fabricated at 0.5 Pa, while the mean crystallite size was 7 nm. The maximum hardness of the deposited coatings was about 47 GPa.

Mechanical and tribological characteristics of multicomponent nitride coverings on the basis of Zr, Ti, Nb, Cr and SiThe multi-component nitride coverings on the basis of (Zr-Ti-Nb)N, (Zr-Ti-Cr-Nb)N and (Zr-Ti-Cr-Nb-Si)N are received by the method of vacuum-arc deposition from multielement cathodes Zr-Ti-Nb, Zr-Ti-Cr-Nb, Zr-Ti-Cr-Nb-Si in the environment of nitrogen (N 2 ). The researches show that chemical composition, microstructure and mechanical and tribological characteristics of coverings are intimately bound to deposition parameters, in particular as: pressure of working gas and potential of shift on the substrate. It is defined that multi-component coverings (Zr-Ti-Cr-Nb-Si)N and (Zr-Ti-Nb)N are simple face-centered cubic solid solution (FCC)). For coverings without Si the structure generally consists of the phase TiN (FCC) and trigonal modification Cr 2 N. The values of hardness were in the range (24-45 GPa). The coverings (Zr-Ti-Nb)N and (Zr-Ti-Cr-Nb) of N provide the best adhesion strength in various conditions of a sliding friction. The coverings (Zr-Ti-Cr-Nb-Si)N showed the worst adhesion strength that is possible to explain with the relative low hardness. The data of coverings are submitted perspective as protective for couples of sliding friction and cutting instrument.

“…Determination of the mechanism of helium ions interaction with the coating material is possible when estimating the energies of the primary knocked out atoms (PKA). The energy E 2 obtained by the target atom in each individual collision is proportional to the energy of the incident ion and is determined by the relation [14,15]:…”

Modelling of parameters of high-fluence ion irradiation of nanostructured TiN, TiAlN, TiAlYN, TiCrN, (Ti-HfZrVNb)N coatings by the Monte-Carlo method was carried out. The obtained results and proposed mechanisms of processes were experimentally proved in studying the structure of the coatings after irradiation with 500 keV He + ions in the fluence range from 5 × 10 16 ion/cm 2 to 3 × 10 17 ion/cm 2. The effect of depth localization of the maximum concentration of implanted helium on nitrogen selective sputtering from coatings as well as on partial flaking (exfoliation) of coatings was observed for the ion fluences higher than 2 × 10 17 ion/cm 2. No phase segregation of the solid solution as the main phase in the nanostructured coatings was found after the ion irradiation. No smarco-or microblistering of the coatings after ion irradiation was found, at least to a blister size approximating the nanoscale.
