不同粘结剂对聚晶立方氮化硼性能的影响研究

摘要

Polycrystalline cubic boron nitride has been widely adopted in the field of ferrous metal processing because of its excellent physical and chemical properties.Binder,as an important constituent of polycrystalline cubic boron nitride,can not only accelerate the sintering process but also affect the performance and aplication of it.The effect and the influence mechanism of the commonly used binders such as Al,Ti and Si during the sinte-ring process have been introduced and the future development of them has been predicted in this article.%聚晶立方氮化硼因具有优异的物理及化学性能，广泛应用于黑色金属加工领域。而粘结剂作为聚晶立方氮化硼的重要组成部分，不仅促进烧结过程的发生，还显著影响其性能及应用。文章介绍了当前常见粘结剂组元 Al、Ti、Si 等元素在烧结过程中的作用及影响机理，并对其未来发展进行展望。
