Mechanical and tribological characteristics of multicomponent nitride coverings on the basis of Zr, Ti, Nb, Cr and SiThe multi-component nitride coverings on the basis of (Zr-Ti-Nb)N, (Zr-Ti-Cr-Nb)N and (Zr-Ti-Cr-Nb-Si)N are received by the method of vacuum-arc deposition from multielement cathodes Zr-Ti-Nb, Zr-Ti-Cr-Nb, Zr-Ti-Cr-Nb-Si in the environment of nitrogen (N 2 ). The researches show that chemical composition, microstructure and mechanical and tribological characteristics of coverings are intimately bound to deposition parameters, in particular as: pressure of working gas and potential of shift on the substrate. It is defined that multi-component coverings (Zr-Ti-Cr-Nb-Si)N and (Zr-Ti-Nb)N are simple face-centered cubic solid solution (FCC)). For coverings without Si the structure generally consists of the phase TiN (FCC) and trigonal modification Cr 2 N. The values of hardness were in the range (24-45 GPa). The coverings (Zr-Ti-Nb)N and (Zr-Ti-Cr-Nb) of N provide the best adhesion strength in various conditions of a sliding friction. The coverings (Zr-Ti-Cr-Nb-Si)N showed the worst adhesion strength that is possible to explain with the relative low hardness. The data of coverings are submitted perspective as protective for couples of sliding friction and cutting instrument.

“…The loads (L C5 ) for the (Zr-TiCr-Nb)N and (Zr-Ti-Cr-Nb-Si)N coatings increase with increasing substrate bias (from −100 to −200 V) their maxima of 62.06 and 45.57 N, respectively. In addition, it should be noted, that coatings, obtained under high bias, possessing the higher hardness are more resistant [53][54][55][56][57]. Nitride coatings (Zr-Ti-Cr-Nb)N and (Zr-Ti-Cr-NbSi)N with good adhesion strength demonstrate high values of hardness, 43.9 and 27.5 GPa, respectively.…”

A B S T R A C TIn this study, (Zr-Ti-Nb)N, (Zr-Ti-Cr-Nb)N and (Zr-Ti-Cr-Nb-Si)N nitride coatings were obtained using a welldeveloped vacuum arc deposition. The systematical investigations demonstrate that the chemical composition, microstructure, and properties of the coatings intimately rely on the deposition parameters (pressure of working gas and substrate bias). Effects of Cr and Si additions on microstructure and mechanical properties of the (ZrTi-Nb)N coatings have been investigated using scanning electron microscopy (SEM) equipped with energy dispersive spectrum (EDS), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), transmission electron microscope (TEM), hardness measurements and adhesion testing. First-principles band-structure calculations and Gibbs-Rosenbaum triangle representation have been used to investigate the elemental and phase compositions in nitride coatings. The multi-component (Zr-Ti-Cr-Nb-Si)N and (Zr-Ti-Nb)N coatings are found to be a simple face-centered cubic (FCC) solid solution. For the coatings without Si, the structure is mainly composed of TiN fcc phase and Cr 2 N trigonal modification. The hardness values were in the ranges (24-42 GPa). The (Zr-Ti-Nb)N, (Zr-Ti-Cr-Nb)N coatings provided the best adhesive strength in different conditions. The (Zr-Ti-Cr-Nb-Si)N coatings exhibited the worst adhesive strength, which may be attributed to the relative low hardness.

“…Low thermal stability and oxidation resistance are among the main disadvantages of such coatings. Addition of impurities to the crystal lattice of the transition metal nitrides form nanostructured coatings with improved properties [25][26][27][28][29][30][31][32]. Ternary nitrides, such as Ti 1-x Al x N, Zr 1-x Al x N and Cr 1-x Al x N have higher hardness, oxidation resistance and thermal stability in comparison with binary CrN, ZrN and TiN coatings [33][34][35][36][37][38][39][40][41][42][43].…”

Phase transformations of Al doped NbN nanocomposite coatings are studied in detail focusing on their microstructural evolution and phase composition. Several techniques such as XRD, SEM, HR-TEM, Nanoindentation and molecular dynamics simulation are employed in order to understand the phase evolution of the Nb-Al-N system. The nanocomposite structures were formed in the coatings, the roughness of the coatings decreased with increasing the Al concentration due to decreasing grain size. First-principles investigation of Nb-Al-N solid solutions was carried out to interpret film properties. It was found, that for small Al fractions, the solid solutions will form in agreement with our experimental results. The spinodal decomposition of Nb-Al-N solid solutions is supposed to be responsible for the formation of the nanocomosite structure observed in the deposited Nb-Al-N films.
