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.

“…It is necessary to improve a set of character istics like strength, brittleness, hardness, and strength of the oxide film adhesion to the surface of the basic metal. The interrelation of mechanical properties of materials, hardness in particular, with the temperature on the surface is discussed in [12,13]. Similar assumptions were made in [14].…”

Abstract-Multicomponent hard coatings based on nitrides of Si doped transition metals have been pro duced by vacuum-arc deposition with the use of a RF generator and separation of an ion-plasma flux. Physico mechanical and tribotechnical characteristics of coatings have been studied. The possibility of their use as efficient protective coatings has been shown. DOI: 10.3103/S1063457614010055Keywords: protective coatings, vacuum-arc deposition, nitrides of metals, cutting tools. INTRODUCTIONOne of the priority directions of the modern science and technology is the development of new materials on the basis of multicomponent alloys, nanocomposite coatings, and analysis of their physico mechanical and tribological characteristics [1,2].To produce multicomponent and multilayer coatings, the ion-plasma deposition methods are most used in the industry, in particular, magnetron sputtering [3] and vacuum arc deposition [4]. The use of ion-plasma methods makes it possible to produce multicomponent coatings of different materials by mixing plasma streams from several sources or by sputtering of a cathode, which contains various components in its compo sition. Of greatest scientific interest are the methods, the use of which makes possible the formation of multi component coatings by conventional devices with one cathode containing necessary components in required ratios. The advances of technologies of applying nanocomposite coatings by ion-plasma methods require a further improvement of the known sputtering systems and development of fundamentally new devices [5,6]. Synthesized multicomponent coatings have high operational characteristics due to the stabilities of the struc ture and composition, which are characterized by the minimum Gibbs energy.Of refractory compounds that demonstrate high functional characteristics nanocrystalline composites pro duced as interstitial solid solutions based on nitrides of titanium, zirconium, hafnium, silicon, etc. take up a special place [7,8].The aim of the present study was to develop superhard multicomponent nitride systems based on solid solu tions produced by sputtering all metal cathodes using a vacuum-arc deposition from a separated beam and RF low energy ion treatment and to study physico mechanical properties of the resulting coatings. The use of separated ion-plasma flux will make it possible to practically get rid of a drop fraction in the coatings formed.

Using the two technologies: plasma-detonation and vacuum-arc deposition, we fabricated two types of coatings: Ti-Si-N/WC-Co-Cr/steel and Ti-Si-N/steel. We found that the top coating of Ti-Si-N was nanostructured one with 12 to 15 nm grain sizes and H = 40 to 38 GPa hardness. A thick coating which was deposited using the pulsed plasma jet, demonstrated 11 to 15.3 GPa hardness, an elastic modulus (E) changing within 176 to 240 GPa, and tungsten carbide grain dimensions varying from 150 to 350 nm to several microns. An X-ray diffraction analysis shows that the coating has the following phase composition: TiN, (Ti,Si)N solid solution, WC, W 2 C tungsten carbides. An element analysis was performed using energy dispersive spectroscopy (microanalysis) and scanning electron microscopy, as well as the Rutherford backscattering of 4 He + ion and the Auger electron spectroscopy. Surface morphology and structure were analyzed using scanning electron microscopy and scanning tunnel microscopy. Tests friction and resistance (cylinder-plane) demonstrated essential resistance to abrasive wear and corrosion in the solution. The decrease of grain dimensions ≤ 10 nm occurring in the top Ti-Si-N coating layer increased the sample hardness to 42±2.7 GPa under Ti 72 -Si 8 -N 20 at.% concentration.
