METHOD OF FORMING METAL MATRIX FIBER COMPOSITES

摘要

The method provides a process for fabricating metal matrix composites. First the process coats the fibers with nickel by electrodeposition or gaseous deposition to form nickel-coated fibers. Over-plating the nickel-coated fibers with aluminum by either electrodep osition in a non-aqueous electrolyte or gaseous deposition forms aluminum-coated-nickel-coa ted fibers. Sintering this product under compression, perpendicular to the fiber's central a xis, forms the final metal matrix composite. The metal matrix composite has a nickel-aluminum m atrix, very few voids and extended unbroken lengths of fibers within the nickel-aluminum mat rix.
