Abstract
A brake rotor for automotive vehicles can be manufactured by a process that involves designing the rotor as two separate sections, forming each rotor section as a separate powdered metal compact, assembling the metal compacts together in a final configuration, and sintering the assembly to densify and bond the rotor sections into a unitary brake rotor body.
Claims3
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.
