“…The plasticity index, which is defined as the hardness (H) to elasticity modulus (E) ratio H/E [7][8][9][10], is also rather high and exceeds the value 0.06. It allows using such coatings as protective under the influence of different alternating loadings and abrasive wear [7,[16][17][18]. For the multilayered TiN/MoN system we found that the lowest value of L c3 critical loading was 42.5 N, and it corresponds to the periodic structure with the biggest period of 100 nm.…”

Using the vacuum-arc evaporation method we fabricated periodic multilayered TiN/MoN structures with different bilayer periods λ ranging from 8 to 100 nm. We found that molybdenum nitride and titanium nitride layers grown on steel show local partial epitaxy and columnar growth across interfaces. A molybdenum-titanium carbide interlayer was evidenced between the substrate and the multilayer. Molybdenum nitride and titanium nitride layers contain small (5÷30 nm) grains and are well crystallized with (100) preferred orientation. They were identified as stoichiometric fcc TiN and cubic γ-M2N. Non-cubic molybdenum nitride phases were also detected. The hardness of the obtained structures achieved great values and maximal hardness was 31÷41.8 GPa for the multilayered structure with a 8 nm period. Hardness of the obtained coatings is 25÷45% higher in comparison with the initial single-layer nitride coatings, plasticity index of multilayered structure is 0.075.

“…While nitrides of single elements are studied well enough, their multilayer modifications need study that is more detailed [26][27][28][29][30][31][32][33][34][35]. Therefore, the study of features of structure, elemental and phase composition of multilayer coatings depending on the deposition conditions is an important task in solid-state physics and materials science [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51].…”

The studies of the structure and properties of nanoscale multilayer coatings based on the nitrides of refractory metals are summarized in a brief review. By the example of TiN/MoN, TiN/ZrN, CrN/MoN, and more complex (multilayer) (TiZrNbTaHf)N/WN:(TiZrNbTaHf)N/MoN obtained by vacuum-arc deposition of cathode, the dependences of their hardness, wear resistance, friction, corrosion, and oxidation on conditions of the deposition and layers' thickness are investigated and analysed. The regularities of the structure and behaviour properties of such nanoscale multilayer coatings depending on the size of nanograins, textures, and stresses arising in these coatings are described.У короткому огляді узагальнено результати досліджень структури та влас-тивостей наномасштабних багатошарових покриттів нітридів тяжкотоп-ких металів.

“…The samples were deposited in nitrogen atmosphere using the vacuum-arc device "Bulat-6" [13]. The evaporated material was a cast in block Zr+Ti+Cr+Nb cathode (composition: Cr -37.39 at.%, Zr -27.99 at.%, Nb -22.30 at.%, Ti -12.32 at.%) fabricated by electron-beam melting.…”

“…For example, if the constituent elements have significant differences in atomic radii, we can expect the formation of nanocrystalline structures. The presence of alloying elements such as Cr improves the oxidation resistance, Zr and V contribute to a better wear resistance, whereas Nb increase the hardness and thermal stability [12][13][14].…”

This work presents the results of (Zr-Ti-Cr-Nb)N superhard coatings research. The samples were fabricated by the vacuum-arc deposition method (Arc-PVD). Structure, composition and properties of these coatings were studied. The study of coatings was carried out using scanning electron microscopy, energy dispersive spectroscopy, and X-ray diffraction. Hardness measurements and adhesion tests were performed. The coatings thickness was up to 6.2 µm, nanocrystallites sizes ranged from 4 to 7.3 nm. Values of hardness and cohesive strength were H = 43.7 GPa and LC = 62.06 N, respectively. The optimal conditions for coating deposition were found.
