  • Process for producing metal/ceramic composite materials
    Patent number: 6520242
    Abstract: A method for producing metal/ceramic composite materials includes an injection plunger; a casting chamber having an opening through which casting metal is poured in and a ceramic precursor product is shot in; and a die having a runner and a die cavity. A shot head is used to shoot ceramic powder into a die, so that the powder is compacted to form a porous preform. The preform is infiltrated with liquid metal under pressure in the die.
