Abstract
In some implementations of the current subject matter, a brake rotor can include a supporting layer applied to a friction surface of a brake rotor substrate, which can optionally include cast iron, and a coating applied over the supporting layer. The supporting layer can include a preparatory metal, and the coating can impart wear and corrosion resistant properties to the friction surface. Related systems, methods, articles of manufacture, and the like are disclosed.
Claims19
A method comprising:
- transferring an amount of a friction material from a brake pad to a friction surface of a brake rotor having persistent surface roughness features, the transferring creating a transfer film layer on the friction surface, the brake rotor comprising a supporting layer applied to the friction surface after formation of an activated layer on the friction surface, the formation of the activated layer resulting from a process comprising back-sputtering of the friction surface, the supporting layer configured to receive one or more coating materials;
- retaining the transfer film layer on the friction surface at least in part due to the persistent surface roughness features;
- and
- stopping a vehicle, the stopping comprising actuating a braking system comprising the brake pad and the brake rotor, the actuating causing the friction material of the brake pad to be urged into contact with the transfer film layer on the friction surface of the brake rotor such that an adherent friction interaction between the friction material and the transfer film layer enhances a braking power of the braking system.

A braking system for a vehicle, the braking system comprising:
- a brake pad comprising a friction material;
- and
- a brake rotor comprising:
- a friction surface having persistent surface roughness features;
- a supporting layer applied to the friction surface after formation of an activated layer on the friction surface, the formation of the activated layer resulting from a process comprising back-sputtering of the friction surface, the supporting layer configured to receive one or more coating materials;
- and
- a transfer film layer located on the friction surface of the brake rotor, the transfer film layer formed from a transfer of an amount of the friction material from the brake pad to the friction surface of the brake rotor, and the transfer film layer retained on the friction surface at least in part due to the persistent surface roughness features,
- wherein actuation of the braking system to slow or stop the vehicle is configured to cause the friction material of the brake pad to be urged into contact with the transfer film layer on the friction surface of the brake rotor such that an adherent friction interaction between the friction material and the transfer film layer enhances a braking power of the braking system.
