文摘

Wettability of WC by liquid binders with various carbon contents was examined. Wettability of WC by a liquid Co-based binder is complete at low carbon content. Wettability of WC by a liquid binder becomes incomplete when increasing carbon content. WC–WC interfaces in high-carbon cemented carbide do not comprise nm-thick Co interlayers. WC–WC interfaces in low-carbon cemented carbide comprise nm-thick Co interlayers.
