“…Figure 5 and Figure 6 show the SEM images of coating surfaces prepared under different arc currents and ion gas flow rates. A large amount of spherical V x C y is dispersed in the surface coating substrate, and inter-dendritic M 7 C 3 eutectic carbides are distributed at the grain boundaries in the intermittent network [ 25 ]. The reason for the reticulation of the hard phase of M 7 C 3 is that the content of Cr is relatively low, so it cannot directly precipitate the M 7 C 3 phase.…”

In this study, we developed composite Fe-Cr-V-C coatings by plasma transferred-arc (PTA) powder surfacing on a 42CrMo steel substrate. The effects of arc current and ion gas flow rate on the coatings’ microstructure, hardness, and bonding performance were investigated. During the surfacing process, VxCy,M7C3M=Fe,Cr and other hard phases are in-situ generated throughout the entire PTA powder surfacing. These phases are uniformly distributed in the Fe matrix through precipitation and dispersion strengthening, yielding a surface hardness of up to 64.1 HRC. Also, the bonding performance between the substrate and coatings was evaluated by measuring the tensile strength, revealing that strong metallurgical bonds are formed, reaching a strength greater than 811 MPa.

“…The reason for this choice is the excellent high-temperature resistance, wear resistance, and corrosion resistance of ceramics. Common additive ceramic phases were TiC, [64][65][66] B 4 C, [67,68] WC, [69][70][71] NbC, [72,73] etc. After the addition of the ceramics, the hardness of the coating became significantly increased as compared with the original HEA coating.…”

With the continuous development of the aviation and aerospace industries, there is an increasing demand for surface coatings that can enhance the wear‐resistance and lubricity of substrates. High‐entropy alloy (HEA) coatings and high‐entropy alloy‐based composite coatings (including ceramic and lubricating phases) have attracted large attention, which is due to their excellent properties. They have, therefore, developed rapidly in the past decade. This article reviews the current status of research on the tribological properties of the HEA coatings and HEA‐based composite coatings that have been prepared by laser cladding technology. The focus is then on the wear‐resistance and wear‐reduction mechanism of the coatings. Furthermore, the review analyzes the influence of element addition, atomic ratio change, and process parameters on the coating organization and properties. The problems that have to be solved in the development of tribology‐based HEAs coatings, and the expected future development of HEA the coatings, are also discussed.

“…Compared with metal alloy powders, ceramic powders exhibit the characteristics of high hardness, high melting point and low toughness and can be used as reinforcing phases in the LC layers. At present, the most commonly used ceramic powders are carbide powders, oxide powders and nitride powders, and the carbide powders include WC, TiC, VC, SiC, NbC, ZrC, and so on [27][28][29][30][31][32]. Rare earths and their oxides are mainly used as modified materials in LC, and the addition of less than 2% can significantly improve the microstructures and properties of the LC layers.…”
