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:
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.
