| Abstract: | The development of WC base cemented carbide with Ni base alloy instead of Co as binder phase in recent years is reviewed.The theoretical foundation and current significance of replacing Co with Ni in cemented carbides are expounded.By means of alloying binder,fining grain size and adding tiny rare earth elements,Ni could take place of Co as binder phase success fully and improve the resistance to oxidization of cemented carbide while providing it with the same strength as that of cemented carbide with Co binder phase . |
