| Abstract: | The advance in functionally graded cemented carbide containing nitrogen with cubic carbide free layer(CCFL),which is used as coating substrate,was reviewed.Some aspects of CCFL were introduced in detail,including the thermodynamic foundation,the gradient structure features,formation mechanism and kinetic progress,mechanical properties and cutting performance.The effects of content of C,N and components on CCFL were commented.Focus on real thermodynamic phase diagrams and kinetic data in alloy system in the future research was proposed. |
| Keywords: | cemented carbide functionally graded material(FGM) cubic carbide free layer(CCFL) mechanism thermodynamics kinetics |
