Abstract
PURPOSE: To provide a composite having fine particles dispersed uniformly in its metallic base. by putting the same kind of metal in a semi-cmolten state as the coarse particles of a metal into a mixture of them and inorganic fine particles under pressure in prefaring of the composite of the metal and inorganic fine particles.
CONSTITUTION: The homogeneous mixture of coarse particles 1 of a metal and dispersed fine particles 2 of graphite or the like is packed into a solid mold vessel, and then, after preheating of the mixture at a specific temperature, the same kind of molten metal as the particles 1 is put into the gaps of the packed layer under pressure with a hydraulic press or the like. The metal pushed by pressure goes into the gaps between particles in a semi-molten state, so that the inside of the mold is filled with the metal. As the metal is in a semi-molten state, it solidifies immediately after that, so that it dos no longer leak out of the mold. Therefore a pressure for pushing the molten metal continues to act sufficiently until the metal solidifies, serving such to bond the molten metal to particles 1 and 2. Therefore the molten metal 3 flows into the mixed layer of particles 1 and 2 and thus the gaps of the layer are filled with the molten metal 3. As the metal of particles 1 and the metal 3 are of the same kind, they are easily united into a body and boundaries between them disappear. Thus, the composite having particles 2 dispersed in its metal base is obtained.
