“…1 (a-d) illustrate a mixed morphology containing fine nodular and small needles, which confirm the dispersion of phases containing cobalt and iron through the coatings. Similar observations have been reported for morphological investigation of other investigations [14][15][16]. The analogous and condensed surface may be due to the utilization of pulse electroplating and the distribution of TiO2 nanoparticles through the sample surface [11].…”

This study is an attempt to produce surface nanocrystalline composite of Fe-Co-TiO2 at various current densities in the range of 20 to 50 mA/cm 2 via pulse electrodeposition method. The prepared composites were characterized by field emission scanning microscope (FESEM), electron dispersive spectrum (EDS), Vickers microhardness, vibrating sample magnetometer (VSM), and x-ray diffraction techniques (XRD). The results showed that the formation of cauliflower morphology was preferred at lower current densities. Moreover, the higher current densities enhanced the Fe content and at the same time diminished the Co and TiO2 contents of prepared surface composites. XRD patterns and Rietveld analysis confirmed the formation of combinations of BCC (as dominant) and FCC phases. Higher current density enhanced the saturation magnetization and decreased lower coercivity due to the higher Fe content and the reduction of TiO2 nanoparticles in coatings. In addition, the lowest coercivity and highest saturation magnetization were gained at 50 mA/cm 2 , while, the maximum microhardness obtained at 30 mA/cm 2 .

“…The authors found a great improvement in corrosion resistance of coatings in the presence of graphene oxide which improved the homogeneity of the HEA coating matrix and prevented localized corrosion [72]. However, despite all this progress, the electroplated HEAs are still in the emerging stage, due to the complexity of processing parameters and multicomponent alloy deposition, which is a tedious task given the interrelated pulse deposition parameters [95,98,100]. Dmitry Moskovskikh et al produced (Hf 0.2 Nb 0.2 Ta 0.2 Ti 0.2 Zr 0.2 )N, which demonstrated outstanding hardness and fracture toughness (33 GPa, 5.2 MPa•m 1/2 ), compared to other reported binary and high entropy ceramics coatings [101].…”

Recently, the materials research community has seen a great increase in the development of multicomponent alloys, known as high entropy alloys (HEAs) with extraordinary properties and applications. In surface protection and engineering, diverse applications of HEAs are also being counted to benefit from their attractive performances in various environments. Thermally sprayed HEA coatings have outperformed conventional coating materials and have accelerated further advancement in this field. Therefore, this review article overviews the initial developments and outcomes in the field of HEA coatings. The authors have also categorized these HEA coatings in metallic, ceramic, and composite HEA coatings and discussed various developments in each of the categories in detail. Various fabrication strategies, properties, and important applications of these HEAs are highlighted. Further, various issues and future possibilities in this area for coatings development are recommended.

Potentiostatic electrodeposition was used to obtain CoCrFeMnNi high-entropy alloy (HEA) thin films on copper substrate. An electrolyte based on a DMSO (dimethyl sulfoxide)-CH3CN (acetonitrile) organic compound was used for the HEA deposition. The microstructure of the high-entropy deposits before and after corrosion in artificial seawater was investigated by scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS) investigation. SEM analysis revealed that compact and uniform film consists of compact and uniform 50 nm–5 μm particles that form the HEA films. The successful co-deposition of all five elements was highlighted by the energy dispersive spectrometry investigation (EDS). Electrochemical measurements carried out in an aerated artificial seawater solution under ambient conditions demonstrated the promising potential for application in the field of anti-corrosion protection, due to the protective behavior of the HEA thin films.
