摘要:

高熵陶瓷是一种新兴的近等摩尔多组元单相固溶体陶瓷材料, 特别是过渡金属碳化物、过渡金属硼化物等过渡金属非氧化物高熵陶瓷体系, 其具有超高硬度、低热导和抗腐蚀等优异的理化性能, 在航空航天、核能和高速切削加工等极端环境有着广阔的应用前景。目前, 高熵陶瓷材料研究尚处于起步阶段, 主要集中在成分设计、制备方法、单相形成能力和力学性能评价等方面, 设计依据和理论方面的研究还相对较少。本文从高熵效应和高熵合金出发, 综述了过渡金属非氧化物高熵陶瓷的制备、表征和理论研究进展, 同时介绍了部分相关的高熵陶瓷涂层研究现状, 总结并展望了非氧化物高熵陶瓷的未来前景和发展方向。

Abstract:

High-entropy ceramics, a novel class of single-phase ceramic solid solutions consisting of near-equimolar multielement species, are recently attracting tremendous attentions. Especially, the transition metal non-oxide high-entropy ceramics, such as transition metal carbide and boride high-entropy ceramics, have been proposed for potential applications in aerospace, nuclear energy, high-speed machining and many other extreme environments, owing to their excellent physical and chemical properties including super-high hardness, low thermal conductivity, good oxidation resistance and corrosion/erosion resistance. Recently, the research of high-entropy ceramics is only focused on composition design, fabrication methods, single-phase stability and mechanical properties, but the design criterion and theoretical analysis are rarely reported. Based on the researches of high-entropy alloy, the fabrication, characterization and theoretical study of several transition metal non-oxide high-entropy ceramics are summarized, along with some related results of high-entropy film. The prospects for the future developments of high-entropy ceramics are also discussed.
