摘要
用 Fe、Ni部分取代 WC- 8Co合金 (牌号 YG8)中的粘结剂 Co,再添加微量稀土 R制得 WC- 8(Fe/Ni/Co) R硬质合金 ,测试了其物理机械性能 ,研究了粘结剂各种成份比例及烧结温度对硬质合金的影响。结果表明 :WC- 8(Fe/Ni/Co) R硬质合金的性能可以达到 YG8的性能标准。利用扫描电镜 (SEM)及 X射线衍射 (XRD)对其作了显微结构分析 ,同时探讨了影响 WC- 8(Fe/Ni/Co) R合金性能的一些因素。
Cemented carbides of the type WC 8(Fe/Ni/Co) R were made by means of adding minor rare earth elements( R ) and a Fe Ni binder (partly substiting for the Co binder) and their physical and mechanical properties were tested. The influences of various compositions and sintering temperatures on the properties of the alloys have been studied. The results indicate that the properties of the WC 8(Fe/Ni/Co) R cemented carbides are comparable to those of the WC 8Co alloys. The microstructures of the alloys were studied using scanning election microscopy (SEM) and X ray diffraction. Some factors that influence the properties of the WC 8(Fe/Ni/Co) R alloys are discussed in detail.
