In this study, CaF2 was introduced into WC-Co to prepare bulk self-lubricating cemented carbides by sinter-HIP. The studied compositions were WC-12Co with no more than 20 vol% additions. effects of on the tribological behaviors and mechanical properties investigated. It found that prepared nearly fully dense would refine WC grains. Although could not obviously enhance carbides, it improved thei...

Cemented carbides are used in the cutting tools industry thanks to their exceptional mechanical properties. Manufactured by powder metallurgy route, they made of a hard WC phase with ductile metallic binder, most commonly Co. Due lower availability Co and its classification as carcenogenic material REACH European Regulation, new binders have be considered: Fe Ni investigated this work. Because ...
