| Abstract: | Bulk binderless ultrafine pure WC with nearly full densification was obtained by spark plasma sintering. The initial uhrafine particle size of about 200nm in diameter was basically maintained after sintering. The Vickers hardness is significantly higher than conventional WC-based cemented carbides. |
