摘　　要：ZrB_2由于具有高熔点、高硬度和良好的导热性,以及在超高温高马赫数冲蚀环境中的优异物理化学性能等,而在C/C和C/SiC等陶瓷基复合材料超高温抗氧化涂层应用领域中得到了广泛的关注,而通过添加化合物改性,可以提高单纯ZrB_2的综合性能。对在ZrB_2中添加的改性化合物进行了分类综述,初步探讨了化合物改性的机理,归纳了硅化物、硼化物、碳化物、难熔金属改性的基本规律,对ZrB_2基陶瓷涂层的改性配方成分设计、性能研究等具有借鉴意义。The ZrB_2 has high melting point,high hardness and good thermal conductivity,as well as excellent physical and chemical properties in UHT high Mach erosion environments.It has been widespread concern in the application areas of ultra-high temperature oxidation resistant coatings of the C/C and C/SiC ceramic matrix composites.The modification by adding a compound can improve the overall performance of simple ZrB_2.This paper reviewed the modified compounds in ZrB_2 by classification,discussed the mechanism of modification of compounds.The basic modification rules of silicide,boride,carbide,refractory metal were discussed.This paper can be a reference in the composition design of ZrB_2 and property research.
