Abstract:
1. A method comprising: surface finishing at least a portion of two 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 to at least the portion of the two parallel surfaces; applying a first material to an area comprising at least the portion of the parallel surfaces through vapor deposition, wherein the first material is deposited onto the area 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 area; and applying a second compound to the area through vapor deposition, the applying comprising energizing a second material source to cause charged particles of the second material source to be dissociated from the second material source, and reacting a reactive gas with the charged particles of the second material to form the second compound applied to the area; wherein the combination of the surface finishing and the applying of the first material and the second compound causes the area of the brake disk to exhibit the predetermined three dimensional surface texture after applying the first material and the second compound.
