“…The fabrication of protective coatings by various deposition methods (chemical processes, physical vapor deposition, ion-assisted deposition) allows to solve plenty of problems in industry regarding approaches to improve wear and corrosion resistance, reduce friction, increase fatigue strength of cutting tools and mechanical details [1][2][3][4][5][6][7][8][9]. Among this variety of strengthening technologies, a special place is occupied by vacuum-arc deposition often named also as cathodic arc physical vapour deposition (Arc-PVD), which makes it possible to obtain coatings suitable for work under high temperatures and pressures, aggressive environment, high corrosion and intensive wear [9][10][11][12][13][14][15][16][17].…”

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.

One area of constant interest in many fields of industry is development of functional multilayer coatings that possess excellent performance characteristics. That is why in our brief review the results of studies of structure and properties of multilayer structures based on binary nitrides of transition or refractory metals obtained by various physical-vapor deposition (PVD) techniques are presented. The influence of substrate temperature, substrate bias voltage, bilayer thickness and interface boundaries on the structure of coatings and their properties, such as hardness, plasticity, wear and corrosion resistance, are discussed in detail. This review may be useful for students and growing community of researchers interested in the synthesis-structure-properties relationship in multilayer coatings based on metal nitrides.

The paper is focused on the deposition and study of multilayered transition metal nitride films CrN/MoN obtained by vacuum arc deposition (Arc-PVD). Samples have from 12 up to 354 layers with total thickness of 8-15 μm. Bilayer thickness of samples vary in range from 2.2 μ to 40 nm. Films have been studied by scanning electron microscopy (SEM) from crosssection view. Their elemental composition also has been studied by energy-dispersive X-ray spectroscopy (EDS). Characterization of the structure of multilayered CrN/MoN films have been performed using X-ray diffraction (XRD) analysis. Two main phases of cubic CrN and-Mo2N have been identified. Grain size distribution was calculated from XRD analysis data. It was observed the decreasing of average grain size with decreasing of individual layer thickness. This feature of studied films may be important for characterization and prediction of their mechanical properties, such as hardness, elasticity, toughness etc. According to the Hall-Petch strengthening, deposited films with lower values of individual layer thickness may have higher values of hardness and, hence, exhibit better toughness, wear resistance and improved performance of coated tools.
