中に分散混入することも不可能であつた。[Prior Art] Conventionally, it was physically impossible to evenly coat ferrite on the surface of ceramic fine particles;
There are no ferrite-ceramic composite particles in which ferrite is evenly coated on the surface of fine ceramic particles, and therefore there is no cast composite material in which a large number of these ferrite-ceramic composite particles are mixed into a metal body. Furthermore, in a cast body, the molten metal body and the ceramic fine particles have different specific gravity and melting point, so it has been impossible to disperse and mix the ceramic fine particles into the metal body.

This is achieved by creating a cast composite material in which a large number of ferrite-ceramic composite particles are dispersed in chromium, molybdenum, aluminum, copper, etc., and by mixing pellets made of ferrite-ceramic composite particles with powder made of metal particles.

がある。 Since the ferrite/ceramic composite particles are granular, the volumetric surface area ratio of ferrite is high, and the magnetic properties per unit mass are improved. In addition, since the ferrite of this ferrite/ceramic composite particle is not a ferrite body obtained by a firing method, there is no change in magnetism even if it is placed under high temperature in a high-temperature reduction furnace. Cast composites mixed with particles have excellent magnetic properties and can be expected to have a wide variety of uses. For example, iron cores, magnets, clutches, electronic parts of electrical products such as motors and transformers, or engine parts, pump cylinders, compressor bearings due to their excellent mechanical properties,
Applications include joints, gears, etc., and heat-resistant, wear-resistant, and corrosion-resistant parts.

A cast composite material comprising a cast body in which a large number of ferrite/ceramic composite particles, in which ferrite is coated on the surface of fine ceramic particles, are dispersed and mixed in a metal body. 2. A step of kneading powder made of ferrite/ceramic composite particles with ferrite coated on the surface of fine ceramic particles with water and/or a binder to form a hard sludge, and a step of granulating this sludge into pellets. , a step of drying the grains to evaporate water to form pellets, a step of mixing and stirring the pellets with powder made of metal particles to form a composite powder, and filling the composite powder into a crucible. A method for producing a cast composite material, comprising the steps of melting the metal at a high temperature in a high-temperature reduction furnace or the like to obtain a molten metal, and flowing the molten metal into a mold and cooling it to form a composite cast body.
