Abstract:
A method of making a brake rotor, wherein said rotor comprises two annular disks and an array of circumferentially spaced fan blades interconnecting said disks; said method comprising;(a) compacting a first mass of contained metal powders to form a first disk-shaped compact;(b) compacting a second mass of contained metal powders to form a second compact having a configuration that includes an annular disk and plural airfoil cross-sectioned fan blades spaced around the disk circumference;(c) assembling said first and second compacts together so that the fan blades are located between the two disks; and placing said first and second compacts in a fixture that prevents relative movement between the two disks, and(d) sintering the assembled compacts to form a unitary brake rotor.
