“…These studies have also reported high wear resistance [9], scratch resistance [10] and thermal phase stability [11]. While a significant majority of HEN coatings are produced by magnetron sputtering [8][9][10][11][12][13], a limited number of studies have investigated the use of cathodic arc evaporation to deposit HEN coatings, including those on (TiZrNbAlYCr)N [14], (TiZrHfVNbTa)N [15], (TiZrA-lYNb)N [16] and (MoNbTaVW)N [17]. Compared to magnetron sputtering which has a lower ion flux and ion energy, in CAE the high current density of the arc discharge produces a plasma with high ion flux and ion energy, which improves the coatings' structure and properties [18].…”

(AlCrTiMoV)N high entropy nitride film was prepared on 17-4PH stainless steel substrate using cathodic arc evaporation (CAE). The composition, microstructure, and thermal stability were investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). Mechanical properties such as hardness and Young’s modulus and coating performance against wear and erosion were also evaluated. The results show that the (AlCrTiMoV)N coating assumes a single-phased solid solution B1 FCC structure. It has excellent thermal stability and retains its structure with no decomposition observed up to a temperature of 1000 °C. The hardness and elastic modulus are measured as 21.3 GPa and 304 GPa, respectively. The coating contains some metallic droplets. As a potential protective coating, the (AlCrTiMoV)N coating has a lower wear rate but a higher erosion rate when compared to the TiN baseline coating.

“…To date, HENs are predominantly produced as thin films [19][20][21][22][23][24][25] , due to their enhanced solubility and phase stability 26 compared to bulk ceramics. Jin et al 27 reported the synthesis of powdered metal HEN V 0.2 Cr 0.2 Nb 0.2 Mo 0.2 Zr 0.2 N 1−x by planetary ball milling a mixture of five transition-metal chlorides with urea and subsequent annealing of the reactive mixture under N 2 flow.…”

Simultaneously hard and tough nitride ceramics open new venues for a variety of advanced applications. To produce such materials, attention is focused on the development of high-entropy ceramics, containing four or more metallic components distributed homogeneously in the metallic sublattice. While the fabrication of bulk high-entropy carbides and borides is well established, high-entropy nitrides have only been produced as thin films. Herein, we report on a newel three-step process to fabricate bulk high-entropy nitrides. The high-entropy nitride phase was obtained by exothermic combustion of mechanically-activated nanostructured metallic precursors in nitrogen and consolidated by spark plasma sintering. The fabricated bulk high-entropy nitride (Hf0.2Nb0.2Ta0.2Ti0.2Zr0.2)N demonstrates outstanding hardness (up to 33 GPa) and fracture toughness (up to 5.2 MPa∙m1/2), significantly surpassing expected values from mixture rules, as well as all other reported binary and high-entropy ceramics and can be used for super-hard coatings, structural materials, optics, and others. The obtained results illustrate the scalable method to produce bulk high-entropy nitrides with the new benchmark properties.

“…Compounds of this type have a high melting temperature, therefore their synthesis in a film state is performed by magnetron sputtering (RF and DC). At the same time, synthesis features of transition metal nitrides and carbides film materials are manifested in dependence of the formed structure and properties on the incident ions energy and the substrate temperature which leads to the formation of film condensates of different structural statesamorphous, cluster, or nanocrystalline [1,2].…”

Research of the effect of structure on composition and physicomechanical properties of transition metals diboride films deposited by RF-magnetron sputtering was carried out. It was shown that there is a wide range of different structures, from amorphous to nanocrystalline one with 1-40 nm nanocrystallite sizes in the case of transition metals diboride films. The correlation between the structure, composition, and physicomechanical properties of transition metals diboride films was established.
