Abstract: Computer simulation was conducted in a VC-doped WC-Co system to understand the diffusion behaviour of W and V atoms in Co binder phase. Different diffusion couples, WC/Co-C, V8C7/Co and WC/Co-V-C were constructed and annealed at temperatures in the range 1100-1300 degrees C. The concentration profiles of V and W atoms in these couples were measured by EPMA, while the diffusion behaviour was also simulated by coupling thermodynamic and kinetic properties of W-C-Co-V system. The simulation results were in good agreement with the measured concentration profiles showing the validity of revised dynamic parameters of W-C-Co-V system. (C) 2006 Elsevier B.V.
