| Abstract Scope |
WC-Co cemented carbide is a metal-matrix composite material consisting of WC and Co binder, which is commonly used in various machining tools due to its excellent hardness and wear resistance. In recent years, high-entropy alloys (HEAs) have been recognized as a new type of binder material due to their excellent mechanical properties. The laser directed energy deposition (L-DED) is an additive manufacturing (AM) process that builds components by simultaneously delivering energy and materials. In this study, influence of processing parameters on microstructures and mechanical properties of WC-CrMnFeCoNi HEA cemented carbide formed by the L-DED were investigated by comparing the WC-Co cemented carbides. This research provides important insights for the processing of the WC- CrMnFeCoNi HEA cemented carbide for surface hardening. It was found that the incorporation of CrMnFeCoNi HEA into the WC cemented carbide as a binder enhanced the hardness significantly. |
