US 2016/0108981 A1 · Wear Resistant Coating for Brake Disks With Unique Surface Appearance and Methods for Coating

Abstract

A brake disk including carbon steel, stainless steel or a ceramic composite material and coated with a coating material that is wear and corrosion resistant and when applied properly allows for the coated surface to have a variety of “textured” appearances. For example, the coated surface can be made to look like woven carbon fiber. The aesthetically pleasing, wear and corrosion resistant coating overlays wear surfaces and portions of the brake disk that will be, in many cases, visible when the brake disk is installed on the vehicle. The coating includes a first layer of a metal, such as a pure titanium metal, and a second layer that can include a Nitride, Boride, Carbide or Oxide of the metal used in the first layer. The coating can be applied using a physical vapor deposition source such as a cathodic arc source with a controlled gas atmosphere.

Dependent claims

A method for manufacturing a coated brake disk having parallel surfaces comprising:

surface finishing at least a portion of the parallel surfaces of a brake disk to impart a predetermined three dimensional surface texture having peaks, valleys and angular surfaces between the peaks and valleys;
applying a first material to at least a portion of the parallel surfaces of the brake disk through vapor deposition, wherein the first material is deposited onto the brake disk by energizing a first material source to cause charged particles of the first material source to be dissociated from the first material source and deposited on the parallel surfaces of the brake disk;
and
applying at least a compound to the at least a portion of the parallel surfaces of the brake disk through vapor deposition, wherein the second compound is deposited by energizing a second material source to cause charged particles of the second material source to be dissociated from the second material source, introducing a reactive gas which reacts with the charged particles of the second material forming the compound that is deposited on the parallel surfaces of the brake disk;
wherein the combination of the surface finishing and the depositing causes the at least a portion of the parallel surfaces of the brake disk to exhibit a selected three dimensional surface texture.
