“…Since then, many authors have studied several HEAs and the evaluation of the different properties. However, most of the authors reported attractive results such as high strength and hardness [ 22 , 23 , 43 , 44 , 45 ], high-temperature oxidation resistance [ 46 , 47 , 48 , 49 , 50 ], high corrosion resistance [ 51 , 52 , 53 , 54 ], high temperature wear resistance [ 21 , 27 , 41 , 50 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 ], unique electrical and magnetic properties [ 68 , 69 , 70 , 71 ] and higher biocompatibility [ 72 , 73 , 74 , 75 ]. Owing to these superior combinations of mechanical and thermal properties, high-entropy coatings (HECs) have been proposed as a prominent solution to mitigate high-temperature tribological issues [ 41 , 56 , 64 , 67 , 76 , 77 , 78 , 79 , 80 …”

Surface coatings that operate effectively at elevated temperatures provide compatibility with critical service conditions as well as improved tribological performance of the components. High-entropy coatings (HECs), including metallic, ceramics, and composites, have gained attention all over the world and developed rapidly over the past 18 years, due to their excellent mechanical and tribological properties. High-entropy alloys (HEAs) are defined as alloys containing five or more principal elements in equal or close to equal atomic percentage. Owing to the high configurational entropy compared to conventional alloys, HEAs are usually composed of a simple solid solution phase, such as the BCC and FCC phases, instead of complex, brittle intermetallic phases. Several researchers have investigated the mechanical, oxidation, corrosion and wear properties of high-entropy oxides, carbides, borides, and silicates using various coating and testing techniques. More recently, the friction and wear characteristics of high-entropy coatings (HECs) have gained interest within various industrial sectors, mainly due to their favourable mechanical and tribological properties at high temperatures. In this review article, the authors identified the research studies and developments in high-entropy coatings (HECs) fabricated on various substrate materials using different synthesis methods. In addition, the current understanding of the HECs characteristics is critically reviewed, including the fabrication routes of targets/feedstock, synthesis methods utilized in various research studies, microstructural and tribological behaviour from room temperature to high temperatures.

“…HEA has attracted widespread attention in recent years which has made HEA become a new category alloy. Michael T. Wall et al [5]performed laser cladding of CoNiFeCrAlTi HEA powder on the surface of the damaged H13 die head, determined the best parameters through experiments, and put the repaired die head into use. The results showed that the life of the die head was significantly improved.…”

For a better performance of the high wear resistance of H13 die steel, FeCoCr1.5NiAl High Entropy Alloy coating was prepared on H13 by laser cladding. The results show that the HEA coating has good metallurgical bonding with matrix. The microstructure of coating is columnar crystal and equiaxed crystal. The coating has the single-phase body-centered cubic and face-centered cubic. The microhardness of this coating is up to 800HV, about 4 times that of the matrix. The friction coefficient of coating is smaller than matrix and the wear volume of coating is decreased approximately 61.02% compared with matrix. The main wear forms of coating is abrasive wear and wear forms of matrix is abrasive wear and fatigue wear.

“…The wear resistance was improved due to phase transformation. Wall et al 11 coated a high-entropy alloy (HEA) CoNiFeCrAlTi on H13 steel die head to evaluate the effectiveness of the clad region and also varied the laser fluence to determine the optimum condition. Xue et al 12 deposited Ni25 alloy (transitional layer) on H13 tool steel by laser cladding and later deposited Fe104 (strengthening layer) alloy over the coating surface.…”

Cladding-based repair has been found to be superior than welding or flame spraying repair approaches in terms of extending die life. In this work, two different alloy powders, that is, CrNiW and CrNiFeAlZr were coated on H13 steel using laser cladding. The laser power, powder feed rate and scanning speed were varied and the clad dimensions, aspect ratio and dilution percentage were measured. The microhardness found in the CrNiW clad is 834 ± 20 HV0.5, which is higher than that of the CrNiFeAlZr clad (780 ± 20 HV0.5) as well as the substrate clad (548 ± 20 HV0.5). CrNiW clad has a higher microhardness than CrNiFeAlZr clad and substrate, indicating that CrNiW laser cladding has a significant impact on microhardness. The interface region for CrNiFeAlZr has 8.33% of C, which is less than the interface region for CrNiW (10.65% of C) so that the microhardness at the interface in CrNiW clad is high. The XRD patterns identified the common phase creation of Ni3C and Fe3C for CrNiFeAlZr and CrNiW coatings, while the oxide formation was only seen in CrNiFeAlZr coatings and the addition of carbon content in the CrNiW clad layer forms WC, Cr23C6, Ni3C and Fe3C. A response surface methodology with a Box-Behnken design is used in the optimisation process.
