Abstract:

Ultrafine tungsten carbide (WC) has the characteristics of high hardness, good wear resistance, high strength and toughness. It is the most basic raw material for the preparation of cemented carbide. Therefore, the preparation of ultrafine WC has become the focus of academic and industrial circles, and also the focus of research in the field of cemented carbide preparation. The preparation technology of ultrafine WC powder and the mechanism of reaction path are reviewed from the perspective of reaction system, and the development trend of ultrafine WC preparation technology is prospected.

Key words: powder, multiphase reaction, ultrafine tungsten carbide, preparation, reaction paths, mechanism

摘要:

超细碳化钨(WC)具有硬度高、耐磨性好、强度高和韧性较高的特点,是制备硬质合金最基础的原料。因此,超细碳化钨的制备成为学术界和工业界关注的焦点,也是硬质合金制备领域研究的重点。从反应体系的角度综述了超细碳化钨粉体制备技术,对相关反应路径机理进行了分析,并展望了超细碳化钨制备技术的发展趋势。
