Abstract:
1. A braking system for reducing particulate emissions resulting from stopping or slowing a vehicle, comprising: a rotating braking element that comprises a bulk structural material and a friction surface, the friction surface comprising a coating that comprises a corrosion and wear-resistant material, the coating comprising a first layer comprising a crystalline material and a second layer overlaying and contacting the first layer and comprising an amorphous material, the rotating braking element further comprising a coarse surface geometry with jagged peaks and valleys under the coating, the friction surface comprising a plurality of raised island formations separated by channels or gaps that permit air flow to cool the rotating braking element during active engagement with the movable brake member; and a movable brake member that comprises a friction material having a friction material composition, the movable brake member being disposed with the friction material disposed opposite the friction surface of the rotating braking element so that the friction material reversibly engages with the coating of the corrosion and wear-resistant material when the braking system is operated to stop or slow the vehicle.
