“…In these coatings, which are usually formed by two types of alternating layers, even if one type of these layers has the high‐entropy characteristic, it will be classified in this category. Some examples of these coatings include (AlCrTiZrNb)N/WS 2 , [ 132 ] AlCrMoZrTi/(AlCrMoZrTi)N, [ 133 ] VAlTiCrCu/WC, [ 134 ] and CrFeCoNi/TiNbZrTa. [ 135 ] As can be seen from their notification, in these coatings, sometimes only one type of layer is high entropic or has a high‐entropy sublattice.…”

High‐entropy metal sublattice coatings (HESCs) prepared by physical vapor deposition (PVD) have received attention due to their diverse range of properties and applications. One of the most critical requirements for their synthesis is the prediction and control of their wide‐spread properties, and several efforts have been undertaken using various thermodynamical parameters. The majority of these predictions concentrate on high‐entropy alloys (HEAs) while high‐entropy ceramics (HECs) received little attention. One of the most important parameters to control the structure and properties of HEAs is their atomic radius mismatch (δr), which we apply to crystalline, amorphous, and composite (amorphous matrix, crystalline matrix, and multilayer) HESCs. Based on the relationships between δr and structure, mixing enthalpy (ΔHmix), electronegativity difference (Δχ), ion bonding percentage (IBPHE), mechanical properties (including hardness, H, and Young’s modulus, E), and wear performance descriptors (H/E and H3/E2 ratios) we provide a δr‐based map to aid the design and selection of elements for HESCs.This article is protected by copyright.

“…The VAlTiCuCr HEA coating has excellent resistance to corrosion, but it lacks abrasion resistance due to its flexibility. Researchers Lu et al [46] used magnetron sputtering to develop unique VAlTiCuCr/WC multilayer coatings on silicon and 304 stainless steels. They investigated the coating corrosion behaviour according to modulation period.…”

Unpredictable deterioration has long been a problem across a wide range of sectors, and it remains so today. High wear-resistant steels, alloys/high entropy alloys (HEAs), composites, and coatings have been the subject of several successful research efforts in recent years. According to this breakdown, the processes of deterioration at elevated temperatures vary greatly from those at room temperature. The attrition resistance of materials was also significantly impacted by their wear resistance, oxidation resistance, and hardness while operating at high temperatures. Therefore, it is necessary to describe in a review the many degradations process of high-temperature materials that exhibit hardness, wear resistance, and oxidation resistance. As a result, this study focuses on the most current improvements, innovations, and wear processes documented for a selection of high-temperature wear-resistant materials.

“…Because of the template effect and coherent growth, the (AlCrTiZrV)N/SiC nanomultilayer film has the better mechanical properties [29], and (TiZrNbHfTa)N/WN multilayered nitride coatings have a higher hardness and Young's modulus [30]. The VAlTiCrCu/WC multilayer coating with a modulation period of 17 nm has better adhesion and wear resistance [31].…”

“…[AlTiCrNiTa/(AlTiCrNiTa)N] 20 high-entropy alloy multilayer coatings have a higher hardness and better high temperature oxidation corrosion [32]. The researchers studied the mechanical properties and oxidation corrosion of HEA nitride multilayer film [30][31][32], but the cavitation erosion of HEA nitrides multilayer films is less reported. Cavitation erosion is one of main reasons for fluid machines.…”

In order to explore the effect of modulation period on the structure and properties of TiSiN/NiTiAlCoCrN nanomultilayer films, the films were deposited on 304 stainless steel via a magnetron sputtering system. The structure and element distribution of the films were observed via X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS). The cavitation erosion of the films was investigated using an ultrasonic vibration cavitation machine. The results show that the TiSiN/NiTiAlCoCrN nanomultilayer film exhibits a face-centered cubic (FCC) structure and preferred orientation on the (200) crystal plane. TiSiN/NiTiAlCoCrN nanomultilayer films grow in the form of columnar crystals, which grow perpendicularly to the direction of the substrate. With increasing modulation periods, the hardness, elastic modulus, and adhesive force firstly increase and then decrease. When the modulation period is 11 nm, the TiSiN/NiTiAlCoCrN nanomultilayer film has the biggest hardness of (14.649 ± 0.591) GPa, elastic modulus of (249.065 ± 10.485) GPa, and adhesive force of 11.3 N. With increasing modulation periods, the mass loss firstly decreases and then increases. When the modulation period is 11 nm, the mass loss is the minimum of 0.6 mg. There are two reasons for improving the cavitation erosion resistance of the films. The TiSiN/NiTiAlCoCrN nanomultilayer film has the highest hardness, and the interfaces of the nanomultilayer film can hinder the generation and expansion of cavitation pits.
