“…The reinforcing phase may be coated to prevent its chemical reaction with the matrix (Sharma et al, 2020). It is noteworthy that the use of HEAs as matrix in metal-based composites is still in the early stage (Sun et al, 2022). HEAs usually contain multi-principal elements in high concentration, thereby hindering their industrial application as bulk materials because of their higher cost compared to the conventional alloys (Fu et al, 2017;Wang et al, 2021b).…”

Energy is a requisite factor for technological advancement and the economic development of any society. Currently, global energy demand and supply largely rely on fossil fuels. The use of fossil fuels as a source of energy has caused severe environmental pollution and global warming. To salvage the dire situation, research effort is geared toward the utilization of clean, renewable and sustainable energy sources and the hydrogen energy economy is among the most preferred choices. Hydrogen energy economy, which includes hydrogen production, storage and conversion has gained wide consideration as an ecofriendly future energy solution with a fuel cell as its conversion device. Fuel cells, especially, the proton exchange membrane category, present a promising technology that converts hydrogen directly into electricity with great efficiency and no hazardous emissions. Unfortunately, the current generation of proton exchange membrane fuel cells faces some drawbacks that prevent them from large-scale market adoption. These challenges include the high costs and durability concerns of catalyst materials. The main source of high cost in fuel cells is the platinum catalyst used in the electrodes, particularly at the cathode where the sluggish oxygen reduction reaction kinetics require high loading of precious metals. Many research efforts on proton exchange membrane fuel cells are directed to reduce the device cost by reducing or completely replacing the platinum metal loading using alternative low-cost materials with “platinum-like” catalytic behaviour while maintaining high power performance and durability. Consequently, this review attempts to highlight recent research efforts to replace platinum and carbon support with other cost-effective and durable materials in proton exchange membrane fuel cell electrocatalysts. Overview of promising materials such as alloy-based (binary, ternary, quaternary and high-entropy alloys), single atom and metal-free electrocatalysts were discussed, as the research areas are still in their infancy and have many open questions that need to be answered to gain insight into their intrinsic requirements that will inform the recommendation for outlook in selecting them as electrocatalysts for oxygen reduction reaction in proton exchange membrane fuel cell.

“…The oxide film acted as a solid lubricant and changed the wear mechanism, thus enhancing the wear‐resistance of the coating. Da et al [ 78 ] tested the wear‐resistance of the CrMnFeCoNi‐TiC composite coatings at 600 °C. The dilution rate of the coatings decreased with an increase in the TiC content, which resulted in an excellent metallurgical bonding quality of the coatings.…”

“…This oxide film acted synergistically with CaF 2 in providing a lubricating friction effect, which reduced the wear rate of the coating by 85% at 600 °C. Sun et al [ 78 ] prepared a CrMnFeCoNi‐TiC HEA‐LC composite coating, which consisted of an FCC structure and TiC ceramic particles. In a friction test at 600 °C, Mn 2 O 3 , Cr 2 O 3 , a small amount of TiO 2 , and TiC formed a composite protective film on the coating surface.…”

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.

“…These two aspects hinder the practical application of MEAs. Laser cladding is an advanced surface coating preparation technique that has been widely used to modify the surface properties of engineering parts [12,13]. During laser cladding, alloy powders and the metal matrix surface simultaneously melt using a high power density laser beam, and then the liquid metal rapidly solidifies to form a cladding layer metallurgically bonded with the matrix.…”

The preparation of functional coatings on metal substrates is an effective method to enhance the surface of steel structures with good serviceability in applications for engineering parts. The objective of this research is to analyze the surface properties of two sorts of medium-entropy alloy (MEA) coatings prepared by laser cladding. After cladding, the two prepared coatings were strengthened by ultrasonic burnishing (UB) treatment. Cladding coating samples before and after being UB-treated were comparatively tested in order to investigate the process effects of UB. When compared with corresponding untreated coating samples, the roughness values of the two sorts of UB-treated samples were decreased by 88.7% and 87.6%, the porosities were decreased by 63.8% and 73.4%, and the micro-hardness values were increased by 41.7% and 32.7%, respectively. Furthermore, the two sorts of UB-treated coating samples exhibited better mechanical properties and wear resistance than corresponding untreated samples.
