Abstract:
Elastomeric seals for use in drill bits on which an inorganic surface modification material has been deposited onto the surface of the elastomeric seals. Wear resistance of the seal at the dynamic surface is improved by providing support for the soft seal surface, by means of the inorganic atoms, against a harder surface.
