摘　　要：过渡金属硼化物因其具有超硬特性而受到人们的关注,有望广泛应用于切屑加工工具、耐磨涂层、研磨材料等领域。介绍了制备过渡金属硼化物块体和薄膜材料的主要方法,并总结了部分过渡金属二元硼化物的结构和性能。不同过渡金属硼化物的结构不同,属于单斜、正交、六方等晶系;过渡金属硼化物薄膜材料的厚度在1μm以下;其硬度高于块体材料的硬度,达到超硬水平;但制得的过渡金属硼化物块体材料的硬度并不理想,与金刚石和立方氮化硼相比尚有一定的差距,还需进一步改进材料设计理念和探索新的制备方法。Transition metal borides obtained more attention for their superhard properties, and could be used as cutting tools, abra- sives and coatings. The preparation methods of transition metal boride bulks and films were reviewed; some of their structures and properties were summarized. Transition metal borides had various structures that belonged to monoclinic, orthogonal and hexagonal sys- tem; the thickness of transition metal borides film was less than 1μm; the film hardness of all borides was higher than that of correspond- ing bulk hardness, reached to the level of superhard; but the hardness of transition metal borides bulks was much lower than that of dia- mond and c-BN. It was recommended to develop material design principle and explore new production process in the future.
