    Opis:
    The effect of implantation of Ne⁺, Kr⁺, and Bi⁺ ions over the energy range 26-710 MeV on the structural-phase state and the mechanical properties of the aluminum-based alloys (Al-Cu, Al-Cu-Mg, Al-Cu-Zn, Al-Mn) was studied. The revealed peculiarities of variations in the structure, phase composition, and mechanical properties of aluminum alloys are attributed to the electron deceleration of ions making the principal contribution to the formation of radiation defects which enhance the diffusion processes in the targets.

    Opis:
    Using X-ray microanalysis and scanning electron microscopy $Zn-Ni-SiO_2$ plating containing $SiO_2$ nanoparticles were studied. It was found that X-ray irradiation of the electrolyte leads to the increased Ni concentration in $Zn-Ni-SiO_2(X)$ films and the grain size is also increasing (the grain size is twice that in the unirradiated case). A thickness of $Zn-Ni-SiO_2(X)$ plating is 20 μm and a thickness of the $Zn-Ni-SiO_2$ plating is about 15 μm. The surface morphology was studied using AFM method. Increasing Ni concentration and $Ni_5Zn_{21}$ phase due to X-Ray irradiation of the electrolyte leading to the improved mechanical properties of the coating.

    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:
    This work presents the results of TiN/MoN coatings studying. These multilayer nanostructured coatings demonstrate dependence on depositions conditions on nanometer level. The influence of nanosized monolayer thickness on structure changing and properties of nanocomposite multilayer coatings TiN/MoN was found. Multilayer TiN/MoN coatings of the total thickness from 6.8 to 8.2 μm were obtained using C-PVD method. Thicknesses of monolayers were 2, 10, 20, 40 nm. The structure of samples was studied using X-ray diffraction (Bruker D-8 Advance) in Cu $K_{α}$ radiation, high resolution transmission electron microscopy with diffraction CFEI EO Techai F200, scanning electron microscopy with energy dispersive X-ray spectroscopy (JEOL-7001F), and microhardness measurements in dependence on indenter load. Scratch tests (friction, wear, etc.) were also provided using Rockwell-C diamond indenter (CSM Revetest Instruments) with a tip radius of 200 μm. Friction and wear behavior were evaluated using ball-on-plate sliding test on a UMT-3MT tribometer (CETR, USA). With decreasing monolayer thickness the hardness value increases, and the size of nanograins reduces. The values obtained for the friction coefficient of the multilayer system is much smaller than in nanostructured coatings of TiN (nc) or MoN (nc). Annealing showed formation of a (Ti,Mo)N solid solution and small growth of nanocrystals.
