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.

“…There are numerous factors that can influence the sputtering of high entropy alloys such as the deposition parameters, substrate temperature, and the post-processing treatment (Mwema et al, 2019;Oladijo et al, 2021;Simon, 2018) , and a summary of the factors that are influencing the sputtered HEA deposition is presented in Table 1. From the Table, power, temperature, substrate bias and pressure are significant process parameters on deposition of HEAs thin films.…”

For the past 19 years, high entropy alloys (denoted as HEAs) have piqued the interest of many researchers due to their unique properties. Sputtering High Entropy Alloys on bulk materials, on the other hand, have been widely utilized due to their low cost of manufacture. This paper reviews the most recent trends and advancements in sputtered HEA coatings, thin film research, and development. Firstly, HEA coating and thin films were introduced. Then, a look at sputtering technologies and procedures is presented, followed by a summary of recent research on sputtered HEA thin films, properties, and applications. From reviewed literature, it can be deduced that HEAs that include the full nitride element have greater mechanical and elastic properties, and HEAs generally have the potential for structural, industrial, biomedical, and energy applications. Finally, it is suggested that new stable HEA films and coating research initiatives with various materials be undertaken to widen its applications.

“…Smooth grains were formed at room temperature in the form of sheets. A FeCoNiAlMnW film deposited at 200 • C showed two types of grains, polyhedral with a size of 100−150 nm and other tiny grains with a size of 20−30 nm [66]. As the temperature increases, the ultrafine grains became larger with a size ranging between 60 and 100 nm.…”

“…Lin et al reported the reduction of residual stress and the annihilation of vacancies in (Cr 0.35 Al 0.25 Nb 0.12 Si 0.08 V 0.20 )N film by increasing the temperature, resulting in improved hardness [28]. In the case of FeCoNiAlMnW film, Sun et al [66] observed a fluctuated variation of the hardness by changing the temperature of the substrate.…”

High-entropy films (HEFs) are of considerable interest in surface engineering applications due to their superior properties, such as good corrosion resistance, good thermal stability and excellent high temperature oxidation. Recently, the scientific community has seen an increasing development of the multicomponent coatings, improving their properties compared to conventional films. Technically, different strategies have been exploited to fabricate HEFs. Magnetron-sputtered HEFs have made significant advancements in this field. HEFs have various applications given their interesting performances. This article overviews the development and the outcome of HEFs prepared using the magnetron sputtering technique. The classification of HEFs is reported. The effect of magnetron sputtering parameters on the microstructural, mechanical, electrochemical and thermal properties of HEFs is also discussed. Applications of HEFs are reported in the last section.
