| Abstract: | Functionally graded hardmetal is one of novel materials emerging in the 1980s,which is derived from the concept of functionally graded materials(FGM) to be applied into the fields of cemented carbides and cermets.The advances in functionally graded hardmetals prepared through diffusion in situ(nitridation process) are summarized,some key issues are focused on,such as metallurgical foundation,composition system,gradient structure types,preparation processes and formation mechanisms of primary type gradient structures,as well as cutting performance.Research in the future is also discussed. |
| Keywords: | functionally graded material(FGM) cemented carbide cermet diffusion cutting performance |
