Abstract
A sintered composite comprises capsule-like powder composite particles composed of core particles and an electrically conductive covering material which covers said core particles. The capsule-like powder composite particles are sintered in a sintering mold while pulsed voltages are being applied to the powder composite particles.
Claims13
A method of manufacturing a sintered composite of a plurality of different materials, comprising the steps of:
- producing capsule-like powder composite particles composed of core particles and an electrically conductive covering material which covers and is adhered to said core particles, the core particles being substantially surrounded by the electrically conductive covering material, wherein said core particles have a melting point different from the melting point of said covering material;
- adding said capsule-like powder composite particles to a sintering mold;
- and
- applying pulsed voltages to said capsule-like powder composite particles in the sintering mold and bonding the capsule-like particles to one another to form a coherent mass, thereby producing a sintered composite.
A sintered composite comprising a solid mass of capsule-like powder composite particles composed of core particles and an electrically conductive covering material which covers and is adhered to said core particles, the core particles being substantially surrounded by the electrically conductive covering material;
- said electrically conductive covering material having a melting point higher than the melting point of said core particles, said capsule-like particles being bonded to one another to form said solid mass.
