Patent ID: 8449943

Claim:
A method for manufacturing a composite coated brake disk having parallel surfaces comprising: applying, by a first vapor deposition process, a first material comprising a metal having a crystalline structure to at least a portion of a surface of a composite brake disk, the composite brake disk comprising a ceramic material, the first vapor deposition process comprising 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 at least the portion of the surface of the composite brake disk; and applying, by a second vapor deposition process, a second material comprising a binary metal compound to at least the portion of the surface of the composite brake disk, the second vapor deposition process comprising 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 to form the binary metal compound that is deposited on at least the surface of the composite brake disk.
