| Abstract Scope |
Cemented carbide composed of Tungsten Carbide(WC) and cobalt metal binder is a representative material for cutting tools because of its superior mechanical properties. There are strong demands for reduction or replacement of Cobalt in different industries due to the recent price hike and supply instability. Therefore, Co-based multi-component alloys are developed as alternative binder in order to reduce the content of Co and improve the mechanical properties of cemented carbide. A mixture of WC and alloy binder was sintered by Spark Plasma Sintering(SPS) at vacuum atmosphere after high-energy ball milling. Microstructures and mechanical properties are analyzed by X-ray diffraction, Scanning-Electron microscopy, Energy-Dispersive Spectroscope and Vickers Hardness tester(30kgf). The WC-CoNiX cemented carbides showed excellent mechanical properties compared to the conventional WC-CO and this suggests that the alternative alloy binders developed in this study have applicability to a new type of cemented carbide for cutting tool materials. |
