    Opis:
    Current paper presents the results of investigating of nanostructured cathode arc vacuum evaporation coatings, based on (Ti, Hf, Nb, Si)N. Several methods of the structural and elemental analysis were used: proton microbeam, nano- and micro-electron beam, X-ray diffraction analysis. To determine tribological properties (scratch resistance, adhesive and cohesive strength) of the coatings, scratch testing were conducting. Influence of thermal annealing at temperatures 300, 500, 800, 1000C on elemental composition, microstructure, residual stress, phase composition, profiles of atomic distribution in the coatings were investigated.

    Opis:
    TiAlN, TiSiN, and TiCrN composite layers were deposited by magnetron sputtering and sliding - angle ion beam sputtering of the inner surface of hollow truncated cones of different compositions. The composition of both type coatings and component depth distributions were studied by the Rutherford backscattering spectrometry. The structural and phase analyses of the deposited films were performed by transmission electron microscopy and diffraction. Microhardness, wear resistance and friction coefficient of the coatings were also measured and discussed in the relationship with the structure and composition. Microhardness tests showed that the registered data varied in the range 10 to 50 GPa, depending on composition and concentration of components. The best wear protection results from the magnetron deposited Ti-Al-N systems in a narrow range of component concentrations. A minimal friction coefficient was revealed for the magnetron sputtered layers.

    Opis:
    Nanostructured thin-film coatings based on titanium nitride, doped with silicon, chromium and aluminium were the object of this study. The creation of a smooth transition layer was carried out by the changing of a supplying nitrogen flow to the vacuum chamber during the application. TiSiN, TiCrN and TiAlN coatings were deposited. The studies of the structure, elemental and phase composition of the coatings were carried out. Also, the performance of coatings was investigated. The results can be used in today's technology, such as mechanical engineering.

    Opis:
    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, $W_2C$ tungsten carbides. An element analysis was performed using energy dispersive spectroscopy (microanalysis) and scanning electron microscopy, as well as the Rutherford backscattering of $\text{}^4He^{+}$ 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.

    Opis:
    This paper presents the first results on formation and study of structure and properties of micro- and nanocomposite combined coatings. By means of modeling the deposition processes (deposition conditions, current density-discharge, plasma composition and density, voltage) we formed the three-layer nanocomposite coatings of Ti-Al-N/Ti-N/$Al_2O_3$. The coating composition, structure and properties were studied using physical and nuclear-physical methods. The Rutherford proton and helium ion backscattering, scanning electron microscopy with microanalysis, grazing incidence X-ray diffraction, as well as nanohardness tests (hardness) were used. Measurements of wear resistance and corrosion resistance in NaCl, HCl and $H_2SO_4$ solutions were also performed. For testing mechanical properties such characteristics of layered structures as hardness H, elastic modulus E: $H^3//E^2$ etc. were measured. It is demonstrated that the formed three-layer nanocomposite coatings have hardness of 32 to 36 GPa and elastic modulus of 328 ± 18 to 364 ± 14 GPa. Its wear resistance (cylinder-surface friction) increased by factor of 17 to 25 in comparison with the substrate (stainless steel). The layers thickness was in the range of 56-120 μm.
