In this study, high entropy nitride thin films of AlCoCrCu0.5FeNi were deposited using RF reactive magnetron sputtering with three different nitrogen gas flow fractions (RN) of 6.25, 12.5, and 25%. X-ray diffraction technique and transmission electron microscopy revealed that the crystallinity of ...
XRD of all 6 carbonitride (left) and 5 nitride (right) compositions. HEN and HECN #1–5 are FCC-rocksalt structures, with some residual native oxides present. HECN #6 shows multiple phases. Intensities are normalized by the highest intensity present in each spectrum. ...

Moreover, the hardness, strength, and abrasion performance of the HEN coatings significantly exceed those of simpler nitride systems [9,10]. It is noted that the super-hard HEN coatings usually contain high amounts of strong nitride-forming elements, like Al, Si, Cr, V, Nb, Ta, Ti, Zr...
High-entropy metal nitrideGrapheneLithiumsulfur (LiS) batteries with ultrahigh theoretical specific capacity (1675 mAh g1) have become a research hotpot, which focuses on the solution of shuttle effect of soluble lithium polysulfides (LIPS). Chemical immobilization of LIPS and encapsulation structure of...
Nitride coatings with high hardness (60.0–65.0GPa) are produced from a high-entropy multicomponent single-phase alloy containing five nitride-forming elements by vacuum arc deposition with application of pulsed implantation. These high values of hardness are characteristic of metals in the equiatomic al...

Although the multi-component ceramics have been of interest for several decades, the concept of high-entropy ceramics was defined in 2004 by producing the first high-entropy nitride films. Following the introduction of the entropy stabilization concept, significant efforts were started to increase the...
