“…On the other hand, the design of multilayer coatings with different composition of bilayers (soft and solid phases) allows to reduce internal stresses and brittleness while high values of hardness from 30 to 45 GPa are maintained [18][19][20][21][22][23][24][25][26][27][28]. One of the promising multilayer systems is the combination of chromium and molybdenum nitrides [29][30][31][32][33][34].…”

The main regularities of the formation of microstructure and properties of multilayer nanostructured CrN/MoN films with periodically changing architecture of layers were considered. The transition metal nitride coatings with high hardness and wear resistance were obtained by vacuum-arc evaporation of the cathodes (Arc-PVD) in nitrogen atmosphere at several sets of predetermined deposition parameters. CrN/MoN multilayers were fabricated using constant nitrogen pressure of 0.4, 0.09 and 0.03 Pa. All samples were divided into three main series depending on the values of bias voltage applied to the substrates (-20,-150 and-300 V). Each serial of samples contain multilayer films varying in the individual layer deposition time and, hence, thickness, which is in range from 1.7 µm to 20 nm. The morphology of surface and microstructure of cross-sections were studied by scanning electron microscopy (SEM). Elemental composition and elemental depth profiles were characterised by energy-dispersive X-ray spectroscopy (EDS), secondary-ion mass spectrometry (SIMS), Rutherford backscattering spectrometry (RBS) and high-resolution transmission electron microscopy (HRTEM) EDS. Micro-and nanostructural analysis of the films was performed by X-ray diffractometry (XRD), grazing incidence XRD (GIXRD), in-plane XRD, electron backscatter diffraction (EBSD) and HRTEM selected area electron diffraction (SAED). The main phases formed in films were two CrN and γ-Mo 2 N nitride phases with cubic lattice of NaCl type and not significant volume of additional metastable MoN cubic phase depending on nitrogen pressure and bias voltage. The preferential orientation of planes changes from [311] to [111] and [200] with the increase of absolute value of bias voltage from-20 V to-150 V and-300 V respectively. The size of nanograins in coatings with a nanometre bilayers thickness was about 12 nm, while micro-deformation of nanocrystallites was about 0.5-0.6%. Coatings with thin nanoscale bilayers have shown high hardness (38-42 GPa) and strong wear resistance, which makes them appropriate and promising for industrial applications as protective ones. The relations between deposition conditions and obtained composition, structure and features were studied. The best parameters and deposition conditions were discussed as recommended to achieve superior mechanical and physical properties of coatings with long lifetime and applicable for harsh environment.

“…To control nanostructured state to a large extent and to improve functional characteristics is possible by projecting multilayer systems with a nanometer modulation period [16,17]. In these systems the improvement of properties is caused by the combination of dissimilar materials.…”

Scanning electron microscopy with energy dispersive element microanalysis, X ray structural analysis, and microindentation were used to study the effect of the deposition conditions in a reactive nitrogen atmosphere on the growth morphology, phase composition, structure, and microhardness of vac uum-arc multilayer coatings produced by the evaporation of cathodes from Mo and (Ti + 6 wt % Si) both after their deposition and after high temperature annealing. It has been established that the use of the composite cathode of Ti and Si allows the formation of the structure state inclined to ordering to form a two phase compound from TiN and Ti 5 Si 3 at high temperature annealing. In this case the coating hard ness increases to a value higher than 45 GPa.

“…Analysis of the literature data shows that one of the ways to improve the physical-mechanical characteristics of coatings is the creation of multilayer structures with a nanometer-thick layer based on transition metal nitrides by transferring them to a nanostructured state [1,2]. Due to the multilayer, as well as by integrating the properties of different layers, you can purposefully influence the structure and properties of the coatings, thereby improving the performance characteristics of products, in particular, cutting tools, machine parts, etc.…”

The tribotechnical characteristics of (TiZr)N/(TiSi)N nitride multilayer coatings obtained by the method of vacuum-arc deposition at room temperature were investigated. The analysis of the influence of the deposition conditions on the mechanical and tribological properties of coatings with different modulation periods (total bilayer thickness) of this structure was carried out: in the 1st series  about 20.4 nm, in the 2nd series with  ≈ 43.9 nm, and in the 3d series of samples the coating was formed with a thickness of  ≈ 137 nm. The results of wear were investigated, and they indicate that multi-element nitride coatings wear out by abrasive mechanism. The intensity of wear in coatings with the number of layers 360 (period   20.4 nm) is 2 times lower than in coatings of 89 layers (period   137 nm). The values of the friction coefficient were 0.79-0.82 during tests. Coating hardness was HV0.05  37.6 GPa for the samples of series 1, HV0.05  31.2 GPa for the second series, and HV0.05  26.5 GPa for the samples of series 3.
