“…In order to obtain the coatings with the strict requirements of high performances and functionalities high-entropy alloys (HEA's) have been proposed [24,25]. In a HEA system, there are five or more elements in equimolar ratio, and the concentration is between 5 and 35 at% for each element.…”

“…It should be noted that, the bulk high-entropy alloys have been investigated more intensive, in contrast to the coatings based on HEAs. There are only few studies on HEA coatings are available, such as: (TiZrNbHfTa)N [25], (AlCrMoTaTi)N [26], (AlCrNbSiTiV)N [27], (AlCrSiTiZr)N [28], (AlMoNbSiTaTiVZr)N [29] and (TiVNbZrHf)N [21]. The nitride films based on high-entropy alloys exhibit beneficial features and extraordinary properties, like excellent mechanical properties oxidation and wear resistance.…”

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.

the paper studies mechanical properties (in particular, adhesion characteristics), as well as wear and failure pattern of nano-structured multilayered composite coating ti-tin-(nbzrAl)n. cutting properties of a carbide tool with the above coating are studied in turning of steel c45, in comparison with an uncoated tool and a tool with reference coating tin. it was found that tool life of the tool with the coating under study is 2.7-3.6 times higher than tool life of the uncoated tool and 1.8-2.2 times higher than that tool life of the tool with coating tin. the conducted microstructural studies have shown a significant difference in wear and failure mechanisms and, in particular, in mechanisms of cracking, for the coating under study and the coating tin. Failure mechanism of coating in the course of the study of strength of adhesion bonds is consistent with its failure mechanism during the study of cutting properties.
