研发WC-Co硬质合金新型的粉末制备方法和烧结技术以开发综合性能优良的硬质合金材料受到了广泛的重视,但关于粉末形貌结构对材料性能的影响还缺乏深入的研究.本文综述了粉末的形貌结构与3种特殊微结构硬质合金,超细/纳米结构硬质合金、中/粗晶粒硬质合金、板晶硬质合金的应用研究进展.
Research on powder preparation methods and sintering technologies for WC-Co cemented carbides with excellent performance has received wide attention,however,the influence of powder morphologies on properties of cemented carbides is also a lack of in-depth study.The powder morphologies,application and preparation of WC-Co cemented carbides with special microstructures,such as ultrafine/nano structure cemented carbide,middle/ coarse grain cemented carbide and plate-like grain cemented carbide,were reviewed.
