WC-based cemented carbides were prepared by spark plasma sintering (SPS) of WC-Co-Cr3C2-VC alloy powder adding different contents graphene. The phase composition, microstructure, mechanical properties, and magnetic properties carbide investigated means XRD, SEM, Vickers hardness fracture toughness tests, tests. results showed that the specimens show a trend first increasing then decreasing with...

WC-Co cemented carbides combine superb hardness with high toughness making them ideal for usage in metal machining and wear resistant tools. Controlling the WC grain size is important during sintering as plays a crucial role mechanical properties of material. Experimental studies have observed different growth rates morphologies W-rich C-rich materials, but mechanism behind this has not been cl...

This work aims to explore WC-G201 high entropy cemented carbides properties fabricated by spark plasma sintering with AlCoCrFeNiTi0.2 and WC as binder phase hard respectively. powder were mixed at the mass ratio of 5: 95, 10: 90 15: 85 respectively, then via SPS 1300℃ for 5min. The results show that has good wettability WC, increase content, hardness alloy decreases gradually, fracture toughnes...

For rock drilling applications, the cemented carbides containing hard WC grains in a ductile Co binder are commonly used as drill buttons. In considering environmental and health aspects an alternate to Co-binder is pursued. present work, using standard scratch testing friction wear properties of WC-20 vol% Ni grade studied compared that grade. The deformation characteristics carbide grades eva...

Tungsten carbide (WC) is the most important tungsten compound, and main component of WC-Co cermet composites. are widely used engineering materials due to combination high hardness strength with toughness plasticity metallic binder. The direct synthesis WC from concentrate containing ∼70% WO3 has been achieved by carbothermic reduction. Mineral/carbon black mixtures were prepared planetary ball...

After WW2, a huge market opened in the growing economies and cemented carbides contributed as tool materials and construction parts to their industrial development. Today, cemented carbides are the workhorses in all areas of the manufacturing industries: no factory without cemented carbide tools; no production of glass bottles, aluminium cans or plastic tubes which has not benefited from these ...

In this study, the correlation existing among grinding, surface integrity, and flexural strength is investigated for WC-Co cemented carbides (hardmetals). A fine-grained WC-13 wt % Co grade and three different surface conditions: (1) ground, (2) mirror-like polished (reference), and (3) ground plus high-temperature annealed, are investigated. Surface integrity and mechanical characterization is...
