Patent ID: 8703661

Claim:
A component comprising: a substrate; and a coating over the substrate, the coating including a plurality of solid film lubricant particles, each solid film lubricant particle comprising at least one compound having the chemical formula M n+1 AX n , wherein M is at least one early transition metal selected from groups IIIB, IVB, VB, and VIB, A is at least one element selected from groups IIIA, IVA, VA, VIA, and VIIA, X is one or both of carbon and nitrogen, and n is an integer between 1 and 3, the plurality of solid film lubricant particles including entirely-surrounded solid film lubricant particles and partially-surrounded solid film lubricant particles, each of the entirely-surrounded solid film lubricant particles surrounded by a coating material having a greater resistance to oxidation than the at least one compound when subjected to a predetermined processing temperature; wherein the coating further comprises a polished contact surface produced pursuant to a controlled polishing process and along which the partially-surrounded solid film lubricant particles are disposed, and wherein the partially-surrounded solid film lubricant particles each comprise an entirely-surrounded solid film lubricant particle from which a portion of the coating material has been removed during the controlled polishing process to expose the partially-surrounded solid film lubricant particle through the polished contact surface of the coating and increase the lubricity thereof.
