Employing MA-FAPAS and using TiAl as exothermal mediate layer, gradient cermets (TiC)pNi and TiAl were synthesized from element reactants in one step as well as the structure of (TiC)pNi/TiAl/Ti was accomplished. The effect of temperature, current and pressure on the process was analyzed. Microstructure observation and composition determination were made by FE-SEM, TEM and XRD. It reveals that well formed and crack-free bond were achieved with strong mutual diffusion of elements across both interfaces. Fracture toughness, thermal shock resistance and bonding strength were evaluated and residual stress distribution was simulated by finite element method. It indicates that the interface between TiAl/Ti has higher thermal resistance and shear resistance than that between (TiC)PNi/TiAl.
