Special Issue Information

Dear Colleagues,

This Special Issue focuses on contributions to improve our understanding of the characterization and efficiency of amorphous and high-entropy alloy coatings based on the relationships between processing and structure with performance, coating design, and size effects. Amorphous and high-entropy coating has acquired important characteristics, including high strength, plasticity, and excellent wear resistance. Several coating techniques, such as magnetron sputtering, plasma transfer, thermal spraying, laser cladding, vacuum evaporation, and electrospark deposition, have also been successfully used to produce a wide range of amorphous and high-entropy alloy coatings on various substrates. Such innovations are expected to enter the coating industry and face the demands of various stress-bearing applications, including those in the mechanical and medical equipment industries. Despite this context, we think that it is significant for us to share the latest findings on amorphous and high-entropy alloy coatings with the scientific community as well as with each other. The topic of interest in the Special Issue includes but is not limited to:

  • Microstructure and features;
  • Mechanical properties;
  • Technologies of coatings;
  • Modeling of microstructure;
  • Industrial applications.

Two magnetron sputter targets of CoCrFeNi High-Entropy Alloy (HEA), both in equal atomic ratio, were prepared by spark plasma sintering. One of the targets was fabricated from a homogeneous HEA powder produced via gas atomisation; for the second target, a mixture of pure element powders was used. Economic benefits can be achieved by mixing pure powders in the intended ratio in comparison to the gas atomisation of the specific alloy composition. In this work, thin films deposited via magnetron sputtering from both targets are analysed. The surface elemental composition is investigated by X-ray photoelectron spectroscopy, whereas the bulk stoichiometry is measured by X-ray fluorescence spectroscopy. Phase information and surface microstructure are investigated using X-ray diffraction and scanning electron microscopy, respectively. It is demonstrated that the stoichiometry, phase composition and microscopic structure of the as-deposited HEA thin films are almost identical if the same deposition parameters are used. Full article
