摘要：

Simultaneous growth of diamond and nickel carbide on a graphite substrate was observed. Nickel carbide appeared as a non-stoichiometric interstitial solid solution possessing the NaCl-type structure. The nucleation and growth of diamond was conducted by microwave plasma chemical vapor deposition. The CH4-H-2 plasma produces intensive mass transport in the separate nickel carbide crystals resulting in coalescence. A hypothesis of the formation of gaseous organometallic molecules is described and the role of atomic hydrogen which alters the Ni-C-H equilibria is discussed.
