    Abstract: A method for producing a composite metal material includes preparing a solution containing a surfactant having both hydrophilicity and hydrophobicity, dispersing a nanosized to micro-sized fine carbonaceous substance into a state of being monodispersed in the solution, bringing the solution having the dispersed fine carbonaceous substance into contact with surface of a metal powder particle, drying the metal powder particle to make the fine carbonaceous substance in the monodispersed state adhere to the surface of the metal powder particle via a component of the solution, and thermally decomposing and removing the solution component adhering to the surface of the metal powder particle by heat-treating the metal powder particle either in a hydrogen-containing reducing atmosphere or in a vacuum atmosphere to partially expose the surface of the metal powder particle out of the adhering fine carbonaceous substance, and thus progress diffusion and sintering among the metal powder particles through exposed parts.

    Abstract: An object of the present invention is to provide a method for producing a dust core wherein generation of iron oxide at grain boundaries in the dust core is unlikely to take place upon annealing of the dust core subjected to compaction, thus allowing excellent electromagnetic characteristics to be realized. Also, the following is provided: a method for producing a dust core, which comprises: a step of molding a magnetic powder comprising a powder for a dust core formed with an iron-based magnetic powder coated with a silicone resin into a dust core via compaction; and a step of annealing the dust core via heating so as to cause the silicone resin contained in the dust core to be partially formed into a silicate compound, wherein annealing of the dust core is carried out at a dew point of an inert gas of −40° C. or lower in an inert gas atmosphere in the annealing step.
