Patent ID: 7975750

Claim:
A method for manufacturing a Coulomb friction damped disc brake rotor, comprising the steps of: providing at least one insert having a coating sprayed thereon; and forming a disc brake rotor in a mold comprising casting molten metal substantially surrounding the at least one insert, wherein a rotor cheek of the disc brake rotor is formed over the at least one insert so that the insert is embedded in the rotor cheek, wherein the rotor cheek has at least one braking surface, and wherein the at least one insert is substantially coextensive with the at least one braking surface; wherein the at least one insert and the rotor cheek provide at least two interfacial boundaries, each interfacial boundary defining an interstice between a rotor cheek inner surface and a surface of the insert and providing a mechanically distinguishable surface boundary between the rotor cheek inner surface and the surface of the insert which are in mutual contact such that a state of Coulomb friction exists therebetween.
