• Thermodynamic calculations

Two main processing technologies of functionally graded (FGM) Ti (C,N)-based cermets, including surface heat-treatment in nitrogen after the vacuum sintering and sintering directly in nitrogen, were reviewed. The characteristics of element distribution, microstructure and performances of the FGM cermets produced by surface heat-treatment in nitrogen after vacuum sintering and sintering directly in nitrogen were summarized. In addition, the forming mechanisms of microstructures were discussed according to thermodynamic calculations, and some suggestions on how to improve the microstructures and performances of FGM Ti(C,N)-based cermets were also proposed.
