Research progress of high-entropy ceramic films and coatings

摘要:

具有五种或五种以上阳离子的高熵陶瓷由于其在各种结构和功能应用中的优异性能，引起了人们的极大关注。在引入熵稳定概念后，人们开始做出重大努力来增加熵，使吉布斯自由能最小化，并实现稳定的单相高熵陶瓷。本文综述了近年来高熵陶瓷薄膜和涂层的最新研究进展。首先从高熵陶瓷薄膜和涂层中的高熵概念出发，介绍了其微观结构；然后概述了高熵陶瓷薄膜和涂层的制备方法，并详细总结了其优异性能的研究成果；最后在此基础上对高熵陶瓷薄膜和涂层进行展望。

Abstract:

High-entropy ceramics with five or more cations have attracted great interest due to their excellent properties in various structural and functional applications. After the introduction of the concept of entropic stability, significant efforts have been made to increase the entropy, minimize the Gibbs free energy, and achieve stable single-phase high-entropy ceramics. This paper reviews the recent research progress on high-entropy ceramic films and coatings in recent years. Firstly, the microstructure of high-entropy ceramic films and coatings is introduced from the concept of high entropy in them; then the preparation methods of high-entropy ceramic films and coatings are outlined, and the research results on their excellent properties are summarized in detail; finally, the prospects of high-entropy ceramic films and coatings are presented on this basis.
