Next,starting from different thermal spraying processes,the research and development status of plasma spraying,supersonic flame spraying,high-velocity arc spraying,and cold spraying on the preparation of HEA coatings were reviewed.Raw material selection, preparation process optimization,performance research,coating post-treatment,and other aspects of the above four thermal spraying techniques to prepare HEA coatings were systematically summarized.Finally,the three problems of limited existing thermal spraying techniques for preparing HEA coatings,limited thermal spraying materials,and aimless design of HEA coatings were proposed. Moreover,three future development issues of new thermal spraying techniques and optimization of existing techniques were discussed along with the development of high entropy ceramics,high entropy amorphous alloys,high entropy composite materials,and other new thermal spray materials.Finally,an HEA database was established to prepare HEA coatings using the concept of material genome to 收稿日期：2020-10-20 基金项目：国家重点研发计划资助项目(2019YFC1908100)热喷涂制备高熵合金涂层的研究现状与展望 辛    蔚，王玉江苣，魏世丞，王    博，梁    义，袁    悦，徐滨士 陆军装甲兵学院再制造技术重点实验室，北京 100072 苣通信作者，E-mail：yjwang201617@163.com 摘    要    首先介绍了高熵合金的理论基础. 然后从不同的热喷涂工艺出发，综述了等离子喷涂、超音速火焰喷涂、高速电弧 喷涂、冷喷涂四种技术在制备高熵合金涂层上的研究发展现状，重点从原料选用、制备工艺优化、性能研究、后处理工艺等 方面对以上四种热喷涂技术制备高熵合金涂层的研究进行系统地归纳与总结. 最后提出现有制备高熵合金涂层的热喷涂技 术较少、热喷涂材料受限、高熵合金设计盲目这三个问题，针对性地提出了在优化已有技术的基础上开发新技术；开发高熵 陶瓷、高熵非晶合金、高熵复合材料等新型热喷涂材料；沿用材料基因组理念建立高熵合金数据库这三点热喷涂制备高熵合 金涂层在未来的发展趋势. 关键词    高熵合金；等离子喷涂；高速火焰喷涂；高速电弧喷涂；冷喷涂 分类号    TG131；TG174.442 Research progress of the preparation of high entropy alloy coatings by spraying XIN Wei，WANG Yu-jiang苣 ，WEI Shi-cheng，WANG Bo，LIANG Yi，YUAN Yue，XU Bin-shi National Key Laboratory for Remanufacturing, Army Academy of Armored Forces, Beijing 100072, China 苣 Corresponding author, E-mail: yjwang201617@163.com ABSTRACT    In  the  1990s,  Ye,  a  scholar  from  China,  broke  the  routine  with  a  creative  idea  of  the  concept  of  high  entropy  alloys (HEAs).  Since  then,  new  alloys,  which  breached  the  traditional  concept  of “ primary  component” ,  have  caught  great  attention  of scientists at home and abroad. Due to their excellent properties such as high hardness, strength, wear resistance, corrosion resistance, thermal resistance, and irradiation resistance, HEAs have been considered as a new generation of thermal spray materials with immense potential for industrial applications. Previous studies show similar or even better properties of HEA coatings compared to those of the HEA block. The preparation of the coatings has become the key point since then. Spraying is one of the common methods on preparing HEA coatings, including conventional methods such as plasma spraying, supersonic flame spraying, high-velocity arc spraying, and cold spraying. With their own advantages and disadvantages, appropriate spraying methods and parameters should be selected according to different matrix and spraying materials, which will be discussed in this paper. First, the theoretical basis of the HEAs were introduced.
