Abstract
A brake rotor includes a one-piece rotor body constructed of stainless steel. The rotor body has a first portion at a central region of the rotor adapted to be coupled to a vehicle's wheel, an annular second portion adjoining and circumscribing the first portion, and an annular third portion adjoining and circumscribing the second portion. The second portion has regions of ablated surfaces. The third portion has opposing braking surfaces. Aluminum coats the regions of ablated surfaces.

A brake rotor for a wheeled vehicle, comprising:
- a one-piece rotor body constructed of stainless steel, said rotor body having a first portion at a central region of said rotor adapted to be coupled to a vehicle's wheel, an annular second portion adjoining and circumscribing said first portion, and an annular third portion adjoining and circumscribing said second portion,
- said second portion having regions of ablated surfaces, and
- said third portion having opposing surfaces adapted for braking engagement with the vehicle's brake caliper;
- aluminum coating said regions of ablated surfaces;
- and
- a material having a thermal emissivity in a range of 0.30 to 0.99 coating said aluminum.
A brake rotor for a wheeled vehicle, comprising:
- a rotor body constructed a monolithic piece of stainless steel, said rotor body having a first portion at a central region of said rotor adapted to be coupled to a wheel hub of a wheeled vehicle, a second portion adjoining and circumscribing said first portion, and a third portion adjoining and circumscribing said second portion,
- said second portion having regions of three-dimensional (3D) stainless-steel ablated surfaces, and
- said third portion having opposing surfaces adapted for braking engagement with the wheeled vehicle's brake caliper;
- aluminum coating said regions of 3D stainless-steel ablated surfaces;
- and
- a material having a thermal emissivity in a range of 0.30 to 0.99 coating said aluminum.
A brake rotor for a wheeled vehicle, comprising:
- a one-piece rotor body constructed of stainless steel, said rotor body having a first portion at a central region of said rotor adapted to be coupled to a wheel hub of a wheeled vehicle, an annular second portion adjoining and circumscribing said first portion, and an annular third portion adjoining and circumscribing said second portion,
- said second portion including radial arms and regions of three-dimensional (3D) ablated surfaces, said radial arms extending between said first portion and said third portion, each of said regions of 3D ablated surfaces disposed between two of said radial arms, wherein an axial thickness of said second portion at said regions of 3D ablated surfaces is less than an axial thickness of said radial arms and less than an axial thickness of said third portion, and
- said third portion having opposing surfaces adapted for braking engagement with the wheeled vehicle's brake caliper;
- aluminum coating said regions of 3D ablated surfaces;
- and
- a material having a thermal emissivity in a range of 0.30 to 0.99 coating said aluminum.
