<P>PROBLEM TO BE SOLVED: To provide a carbon nanotube or carbon nanofiber (CNT or CNF)-containing composite metallic material having excellent hardness, strength, electric conductivity and wear resistance by a simple process. <P>SOLUTION: Dimple-shaped or line-shaped grooves are made in the surface of a metal, CNTs or CNFs having a sheet shape or a paste shape or subjected to printing application are inserted into the surface thereof so as to be a sandwich shape, and heat and pressure are applied directly until before the compositional change of the CNTs or CNFs occurs. This operation is repeated, and CNTs or CNFs are mixed into the raw material metal in a uniform state, thus a metal nanocomposite material is produced. <P>COPYRIGHT: (C)2011,JPO&INPIT |
