METHOD OF FORMING METAL MATRIX FIBER COMPOSITES

摘要

The method provides a process for fabricating metal matrix composites. First theprocess coats the fibers with nickel by electrodepos ition or gaseous deposition to form nickel-coated fibers. Over-plating the nickel-coated fibers with aluminum by either electr odeposition in a non-aqueous electrolyte or gaseous deposition forms aluminum-coated-nickel -coated fibers. Sintering this product under compression, perpendicular to the fiber's centr al axis, forms the final metal matrix composite. The metal matrix composite has a nickel-alumin um matrix, very few voids and extended unbroken lengths of fibers within the nickel-aluminum matrix.
