ABSTRACT:
A tone ring of a vehicle anti-lock braking system of the type that is integrated into a disc brake rotor. The tone ring has a protective layer which enables it to withstand the combination of extreme heat and harsh environmental conditions to which it is exposed during operation of the vehicle. The protective layer is applied by thermally spraying a selected one of a plurality of materials, such as a nickel-based alloy, a high-chrome stainless steel, or non-ferrous materials such as an aluminum, copper-based alloys or a ceramic, on teeth of the tone ring, and without causing the protective layer to be deposited on the rotor braking surfaces. The protective layer generally prevents the formation of oxidation and corrosion byproduct layers on the teeth, to thereby maintain sensitivity for detection of teeth movement by the anti-lock braking system sensor during operation of the system.
