摘　　要：本文以再生WC粉混合制备YG8硬质合金为研究对象,对硬质合金性能和组织进行分析。结果发现,与原生WC粉末制备的硬质合金相比,再生粉末制备的硬质合金矫顽力有所提高,而钴磁和抗弯强度等性能下降明显;金相分析发现组织中出现明显的脱碳现象。In this paper,YG8 cemented carbides prepared by regeneration WC powder is taken as the object of research,and the properties and microstructure of the cemented carbide are analyzed.The results show that compared with native WC powder,the cemented carbide prepared by regeneration WC-Co powder has better coercive force,magnetic cobalt and bending strength decline.The obvious decarburization phenomenon is observed by metallographic analysis.
