  • Patent number: 5846664
    Abstract: A process is provided for the manufacture of porous metal components. The process involves preparing a colloidal suspension comprising a metal-containing powder in admixture with a binder system, and a plasticizer in an organic solvent. Optionally, a particulate pore forming agent may be added to the suspension. The suspension is cast into a thin sheet and air dried to thereby form a tape. The tapes are layered and formed by compacting at predetermined pressures to laminate the tapes, thus forming a green body. Optionally, a second pore-forming agent may be introduced between, or associated with, the tape layers. The green body is heated at a controlled rate to form a brown body, and finally sintered under controlled conditions to produce the finished component.
