Design, Characterization, and Application of High-Entropy Alloy Coatings

Dear Colleagues,

Surface coating and modification of industrial components can yield a more profitable return in a much shorter time compared to the painstaking and laborious processes of inventing novel materials. With surface modification, their physical, mechanical and chemical durability would be improved. From an economic point of view, surface coating is considered an inexpensive process because only the surface layer needs to be modified. In other words, with surface coating, the key features of a part can be retained while only the outermost surface is modified to tailor to the desired properties. High-entropy alloys (HEAs), newly developed metallic materials with equimolar or non-equimolar compositions, have recently gained attention owing to their superior properties. HEAs are a novel alloy concept beyond the realm of the traditional alloys that exhibit excellent and functional physical and mechanical properties such as high hardness and tensile strength, corrosion, and wear resistance. Compared with the conventional metallic alloys composed of one or two major and some minor elements, HEAs consist of more than four principal elements. In spite of ever-increasing knowledge about the mechanical and physical properties of bulk HEAs, proving a systematical approach for understanding the potential of the high-entropy alloys coating and optimizing their properties are also essential. Considering the fact that numerous parameters such as the design and composition, and coating techniques, can alter the microstructure and properties of the HEAs, it is believed that this Special Issue could be a promising opportunity for the researcher and scientific communities to present their recent findings on HEAs coatings and their applications.

The main scope of the current Special Issue will include but not be limited to the following concepts:

• Theoretical and experimental research, knowledge, and new ideas in designing and synthesizing HEAs coating.
• Modeling and simulation to predict the coating features, performance, durability, and reliability in service environments.
• Coating methods such as Thermal Spray techniques, Cold Spray, PVD, CVD, Laser Cladding, and Plasma Arc Depsoitio etc.
• Durable, Wear, and Corrosion Resistance HEAs coatings
• Thick coatings and Thin Films
• Catalytical Application of HEAs coatings
• Biomedical and Biological Application of HEAs coatings
