ABSTRACT:
The present invention relates to a method of manufacturing a metal-impregnated body in which a porous body is immersed under sub-atmospheric pressure in a molten alloy for impregnation with said alloy or a porous body is immersed under elevated pressures produced by various gases, the pressure then being reduced to normal level, after which the porous body is introduced together with a molten alloy into a metal mold, in which said molten alloy is impregnated into said porous body. The porous body is then separated from said molten alloy.
