This invention provides a transition metal covered carbon material comprising a transition metal covering. In the transition metal covered carbon material, the adhesion between the transition metal and the carbon material is large, and the transition metal covering is less likely to be separated or eliminated during subsequent working. The transition metal covered carbon material is produced by depositing a compound containing a transition metal ion on the surface of a carbon material, heat treating the assembly to reduce the transition metal ion with carbon contained in the carbon material to form a transition metal as a simple substance. The transition metal is Fe, Co, Ni, Mn, Cu, or Zn. There is also provided a carbon-metal composite material using the transition metal covered carbon material, which has improved affinity for metal such as aluminum and has excellent mechanical strength and thermal conductivity. |
