US Patent 7918713 Tribological surface and lapping method and system therefor

A conditioning process including the steps of: (a) providing a system including: (i) a workpiece having a metal working surface; (ii) a contact surface, disposed generally opposite the working surface, the contact surface including an organic, polymeric material and (iii) a plurality of particles, including abrasive particles, the plurality of particles disposed between the contact surface and the working surface, and (b) treating the workpiece so as to: (i) effect an at least partially elastic interaction between the contact surface and the abrasive particles such that at least a portion of the abrasive particles penetrate the working surface, and (ii) incorporate organic particles into the metal working surface, thereby producing a modified working surface, wherein the treating of the workpiece includes a lapping process including: (i) exerting a load on the contact surface and the metal working surface, and (ii) applying a relative motion between the metal working surface and the contact surface.
