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 organinc 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.

Abstract: The invention concerns the manufacture of dense sintered products by sintering green compacts which have been sintered from powder material in a vacuum and subsequently compressed by hot isostatic pressing (HIP). The invention calls for an inert gas to be passed round the green compacts during the vacuum-sintering stage, while still maintaining a low pressure of between (1) and (10) mbar. A suitable device for carrying out this process has inert-gas feed line (18) leading into the sample container (16). After passing round the compact(s) (17) being sintered, the gas is removed from the pressure chamber through a suction line (20).

Abstract: A method of producing cemented carbide or cermet alloy comprising mixing and kneading cemented carbide powder or cermet alloy powder with an organic binder, molding this mixed powder into a predetermined shape by injection molding, removing the organic binder from the resulting mold and sintering the mold to obtain a compact alloy. The removal of the organic binder is carried out in a first removing step in an inert gas atmosphere and subsequently in a second removing step in vacuum of 1 Torr or below. In the first removing step, the pressure of the atmosphere is kept at or above the atmospheric pressure so as to prevent the occurrence of defects in the mold. After continuous fine pores are formed inside the mold, the pressure of the atmosphere is kept near vacuum in order to promote the evaporation of the gas from the surface and the release of the gas generated inside the mold.
