The nucleation of carbide (Cr, Fe)(7)C-3 on the Cr3C2 particle in the Cr3C2/Fe-CrNiBSi composite coating was studied. It was found that there were a great deal of craters on the surface of half-dissolved Cr3C2 particle, and plenty of carbide (Cr, Fe)(7)C-3 buds nucleated and grown out there. The analysis of crystallographic relationship shows that the lattice misfit between (013)(Cr3C2) and (10 (1) over bar0)((Cr,Fe)7C3) is 8.66%, indicating Cr3C2 can efficiently act as the heterogeneous nuclei of (Cr, Fe)(7)C-3.
