Description
Technical Field

Background
The proposal of the high-entropy alloy concept provides infinite possibility for vast material researchers to design novel alloy systems. The refractory high-entropy alloy composed of the early transition group metal elements has the advantages of high average melting point, strong hardness and the like, is considered as a new generation of high-temperature structural material, and has potential application prospects in the aspects of turbine blades, refractory materials and the like. At present, most of researches on refractory high-entropy alloys are focused on bulk materials, and relatively few researches on coatings are carried out. However, the refractory high-entropy alloy is usually rich in a large amount of precious metal elements, which greatly increases the manufacturing cost; meanwhile, the high average melting point greatly increases the smelting and casting difficulty of the block material. Therefore, the preparation of small-sized coating or film samples would be effective in solving the above problems.
