Abstract
The invention provides a method for manufacturing a friction damped disc brake rotor, including the steps of: (A) providing a ceramic coating on an insert, wherein the insert has a body with tabs extending therefrom to hold the insert in a desired position within a mold; (B) washing the ceramic coating off of the tabs; (C) positioning the insert into the mold; and (D) casting a rotor cheek of the disc brake rotor in the mold around the insert such that a portion of each tab is bonded with the rotor cheek, and such that the coating is substantially non-bonded with the rotor cheek so that the coating provides a proper interfacial boundary between the body and the cheek for damping, and the at least partial bonding of each tab with the rotor cheek prevents corrosion-causing exterior elements from reaching the interfacial boundary when the friction damped disc brake rotor is in use.
