Abstract	The WC-Co composite nano-coatings bonded strongly with steel substrate has been made by vacuum fusion sintering (VFS). Diffusion plays a crucial role in VFS processes, of which the atoms diffusion nearby interface is a vital variable which influences the interfacial bond strength. The atoms diffusion during the vacuum fusion sintering (VFS) process was firstly studied by molecular dynamics and by Fick second law of diffusion. The three-dimensional MD model was built, by which the atoms diffusion, atoms migration contrail and the VFS process were simulated. The concentration distribution of some components were measured by the electrical probe, and the microstructure and morphology of VFS nano-coatings were observed and analyzed by SEM, X-ray diffraction meter and micro-hardness instrument. Combined with the experimental results, diffusion coefficient of every element was calculated in diffusion dynamics
