“…According to the reported methods for preparing HEA coatings, the surface modification techniques include electrochemical deposition ( Soare et al, 2015 ), physical vapor deposition (PVD) ( Khan et al, 2020 ; Xia et al, 2020 ), laser cladding ( Zhang et al, 2017 ; Guo et al, 2018 ; Wang L. et al, 2019 ), plasma cladding ( Anupam et al, 2019 ; Peng et al, 2019 ; Zhu et al, 2020 ), and thermal spraying ( Wang et al, 2011 ; Vallimanalan et al, 2020 ), etc. Particularly, the magnetron sputtering and laser cladding in the biomedical field are two relatively promising technologies for the preparation of HEA coatings.…”

With the continuous progress and development in the biomedicine field, metallic biomedical materials have attracted the considerable attention of researchers, but the related procedures need to be further developed. Since the traditional metal implant materials are not highly compatible with the human body, the modern materials with excellent mechanical properties and proper biocompatibility should be developed urgently in order to solve any adverse reactions caused by the long-term implantations. The advent of the high-entropy alloy (HEA) as an innovative and advanced idea emerged to develop the medical implant materials through the specific HEA designs. The properties of these HEA materials can be predicted and regulated. In this paper, the progression and application of titanium-based HEAs, as well as their preparation and biological evaluation methods, are comprehensively reviewed. Additionally, the prospects for the development and use of these alloys in implant applications are put forward.

“…The contribution of individual elements for making high entropy alloy is as listed in Table 2. The motive behind selecting a particular individual element for the preparation of high entropy alloy is mixing enthalpy of every principal element with each other, as listed in Table 3 [16].…”

“…Therefore, the temperature difference (∆t) is very high, while the solidification rate (r) is less, which tends to give large ∆t/r. Therefore, the nucleation rate is much quicker than the growth rate of the crystal and it will lead to grow as the planar crystal at the interface [16][17][18]. The growth direction of the columnar grain is perpendicular to the interface zone due to the rapid directional solidification, typical of the laser cladding process [19].…”

“…Additionally, high proportion of Cr is observed in interdendritic region indicating partial dissolution of tungsten carbide particles and replacement of W with Cr. This could be majorly due to the capillary phenomena of melted material and concentrated laser energy, which may tend to increase in the temperature of the molten pool beyond the melting point of tungsten carbide particles and lead to the partial dissolution of tungsten carbide particles [16]. Figure 5 shows the EDS elemental mapping for the individual elements in the cladding layer.…”

“…However, the investigation regarding HEA coating strengthened by reinforcing phase particles are limited. WC has very high hardness (2600 HV) and melting point (2600 o C) making it ideal as a reinforcement material in HEA coating to enhance mechanical characteristics [11,16]. In present work, a novel high entropy alloy coating with an equiatomic composition of AlFeCuCrCoNi-and 10 wt.% WC (AlFeCuCrCoNi-WC10) was deposited on AISI-316 substrate through laser cladding.…”

In spite of excellent corrosion resistance, good ductility and low cost of AISI 316 austenitic stainless steel, the low hardness and poor mechanical characteristic of material restricts its applicability in several industrial services. To improve the mechanical properties AlFeCuCrCoNi-WC10 high-entropy alloy coatings were deposited via laser cladding on austenitic stainless steel AISI 316 substrate. The influence of WC on phase constituents, microstructure, microhardness and elemental distribution were investigated using X-ray diffractometry, optical microscopy microhardness tester and FESEM-EDS (Energy Dispersive Spectroscopy), respectively. The XRD peaks revealed that as clad AlFeCuCrCoNi-WC10 multiple principal element alloy coating composed of BCC, FCC and W-rich phase. The cladding zone microstructure is mainly consisting of fine-grained non-directional and equiaxed crystals away from the base material and columnar grains near the base material. The energy dispersive spectroscopy indicated segregation of W and Cr in the interdendritic region. However, other elements of the multiple principal element alloy are observed to be uniformly distributed throughout the cladding. The microhardness of the AlFeCuCrCoNi-WC10 (670 Hv0.5) high entropy alloy coating was 4.5 times greater than that of substrate AISI-316.
