ABSTRACT In the past 14 years, as a branch of high-entropy alloy (HEA) materials, HEA films and coatings have exhibited the attractive and unique properties, relative to the conventional film and coating materials. The recent research and development of HEA films and coatings are reviewed in this paper. At first, the basic concept of HEAs films and coatings are introduced. Then, their preparation technologies, microstructures and appealing properties are summarized. Moreover, the possible reasons and design criteria for achieving the excellent properties are discussed. Finally, the suggested future research work for the HEA films and coatings are outlined. GRAPHICAL ABSTRACT IMPACT STATEMENT Preparation technologies, microstructures, and properties of HEA films and coatings are reviewed in this paper. The design criteria and suggested research directions are further discussed and proposed.
