聚晶立方氮化硼的制备方法及应用进展

摘要

Preparation methods of polycrystalline cubic boron nitride(PCBN) and its compact,as well as industrial application, were summarized. The sintered-type, growth-type and growth-sintered preparation of PCBN were discussed.Direct conversion method,brazing method and once sintering method in preparation of PCBN compact were compared.PCBN application in automobile,bearings, tools and other industries were reviewed.Finally,the future development trend of PCBN and PCBN compact was prospected.%对近年来国内外聚晶立方氮化硼(polycrystalline cubic boron nitride,PCBN)及其复合片的制备方法和工业应用进行了综述,主要介绍了烧结型、生长型和生长–烧结型聚晶立方氮化硼的制备方法；系统论述了采用直接转化法、钎焊法和一次烧结法制备聚晶立方氮化硼复合片的进展；并对聚晶立方氮化硼在汽车制造、轴承和超精密工具等行业中的应用进行了概述。最后,对聚晶立方氮化硼及其复合片未来发展方向进行了展望。
