摘要
综述了硬质合金表面钴梯度材料设计思想、钴相迁移机理和两种主要制备工艺,即脱碳(氮)和渗碳(氮)工艺,并概述了这类材料的研究开发意义。
The idea for designing and the mechanism of cobalt-phase removal of cemented carbidematerial with cobalt gradient on the surface and two chief preparation processes which aredecarburization or denitrification and carburization or nitrizing are described. The magnifi-cence of research and development of this kind of material is summarized.
