| 15. A lapping method comprising the steps of:
(a) providing a system including:
(i) a metal workpiece having a metal working surface;
(ii) a polymeric material having a polymeric contact surface, said contact surface disposed generally opposite said working
surface, said contact surface for moving in a relative motion to said working surface;
(iii) a plurality of abrasive particles, said particles disposed between said contact surface and said working surface, and
(iv) a solid lubricant, associated with said polymeric contact surface;
(b) exerting a load normal to said contact surface and said metal working surface,
(c) lapping said workpiece by applying a relative motion between said metal working surface and said contact surface, under
said load, to:
(i) effect an at least partially elastic interaction between said contact surface and said abrasive particles, wherein at
least a portion of said abrasive particles penetrate said working surface to produce a metal tribological working surface,
and
(ii) enhance at least one tribological property of said tribological working surface by means of said solid lubricant associated
with said contact surface.
