A kinetic model for carbide diffusion coating has been proposed bused on the theory of steady diffusion and the sublattice model of solid solution.It is supposed that the growth rate of car- bide layer is controlled by the volume diffusion coefficient of carbon (?)s in carbide layer and the activity of carbon in steel substrate.The calculated results for V_4C_3 coating treatment of commercial steels T10.45,Crl2MoV,4Cr5MoVSi are in good agreement with the exper- imental data.
