Fe-Ni-C alloy%synthetic diamond%metallic film%interface
Microstructures of surface layer (near diamond) of the metallic film from Fe-Ni-C system are composed of (Fe,Ni)3C, (Fe,Ni)23C6 and γ-(Fe,Ni), from which it can be assumed that graphite isn't directly catalyzed into diamond through the film and there exists a transition phase (Fe,Ni)3C that can decompose into diamond structure. AFM morphologies on the film/diamond interface are traces preserved after carbon groups moving from the film to diamond. The morphologies on the as-grown diamond are similar to those on corresponding films, being spherical on (100) face and sawtooth-like steps on (111) face. Diamond growth rates and temperature gradients in boundary layer of the molten film at HPHT result in morphology differences.
