| Summary: | The failure of metallic materials often originates from their surface. Surface strengthening technology can effectively extend the service life and improve the working efficiency of metal components. High-entropy alloy coatings exhibit significant advantages of uniform composition, dense structure and stable structure through the size effect induced by their unique low-dimensional forms(such as films or nanoparticles), which synergizes with their multi-principal component characteristics. The size effect effectively enhances the overall performance of coatings by influencing their interfacial stress distribution, surface energy, and defect evolution. This paper systematically reviewed the primary fabrication techniques of high-entropy alloy coatings, thoroughly investigated their microstructural characteristics and service performance, and analyzed the intrinsic correlation mechanisms among composition, processing methods, microstructure and properties. Meanwhile, the application value of numerical simulations in coating preparation, microstructural evolution, and performance characterization was further elaborated, and perspectives were provided on future research directions and engineering applications of high-entropy alloy coatings. Generally, the study aimed to clarify the preparation pathways and performance evolution laws of high-entropy alloy coatings, reveal their strengthening mechanisms and the correlation between composition, processing and performance, explore the application of numerical simulation in coating design and optimization, and provide theoretical support for their engineering applications. |
