Abstract
A metal matrix composite is produced by rapidly solidifying an aluminum base alloy directly into wire. The wire is arc sprayed onto at least one substrate having thereon a fiber reinforcing material to form a plurality of preforms. Each of the preforms has a layer of the alloy deposited thereon, and the fiber reinforcing material is present in an amount ranging from about 0.1 to 75 percent by volume thereof. The preforms are bonded together to form an engineering shape.
Claims34
A process for producing a rapidly solidified aluminum base metal matrix composite, comprising the steps of:
- (a) forming a rapidly solidified aluminum base alloy into a wire, said wire being formed directly during rapid solidification of said aluminum base alloy by casting a melt of said alloy into a fluid quenching medium;
- (b) arc spraying said wire onto at least one substrate having thereon a fiber reinforcing material to form a plurality of preforms wherein each of said preforms has a layer of said alloy deposited thereon and said fiber reinforcing material is present in an amount ranging from about 0.1 to 75 percent by volume thereof:
- and
- (c) bonding said preforms to form an engineering shape.
A composite comprised of a plurality of preforms bonded to form an engineering shape, each of said preforms comprising a substrate having thereon a fiber reinforcing material upon which an aluminum base alloy layer is deposited, said alloy having been rapidly solidified and formed directly into a wire by casting a melt of said alloy into a fluid quenching medium and deposited by arc spraying, and said fiber reinforcing material being present in an amount ranging from about 0.1 to 75 percent by volume thereof.
