Article history: Received 9 November 2015 Accepted 25 April 2016 Available online 27 April 2016 Nanostructured WC powders can provide technologically attractive properties due to the fine microstructures obtained after sintering. Either W or WO3 powders are used for the industrial production of WC. In both cases, the contact area between carbon and tungsten precursors has a critical influence o...

This study focuses on the preparation of fine-grained WC/Co composite powder using rolling ball milling and spray drying techniques. The cemented carbide composition achieved through low-pressure sintering technology was WC-10Co-0.5Cr3C2-1TaC-0.5Ru (wt.%). To effect temperature microstructure mechanical properties WC-10 wt.% carbide, phase constituents material were analyzed X-ray diffractometr...
WC-10Co cemented carbides containing 1 to 4 wt% SiC nanoparticles were prepared by spark plasma sintering. The effects of SiC content on microstructure, mechanical properties and wear resistance of the sintered materials were studied. Microstructural studies showed that SiC addition resulted in WC grain coarsening. In addition, the hardness decreased with increasing SiC content. However, the fr...
