ABSTRACT:
A method of fabricating a metal matrix composite containing electrically isolated areas and the MMC formed from the method. The method comprises: (a) providing a liquid pool of unreinforced aluminum alloy; (b) infiltrating the unreinforced aluminum alloy into a stack comprising upper and lower porous preforms and an electrical insulator material placed between the preforms; (c) solidifying the liquid-phase metal to form a metal matrix composite product that completely surrounds the stack; and (d) forming at least one groove in the solidified metal, the groove extending downward to at least one insulating substrate so as to electrically isolate at least one region on the surface of the metal matrix composite.
