A method of repairing a worn carburized surface on a sprag clutch comprising the steps of: grinding the worn carburized surface of the sprag clutch to prepare the surface for metallurgical bonding; place the worn carburized surface in a PVD Cathodic Arc chamber; preheat the worn carburized surface to remove moisture and provide for a good metallurgical bonding surface; reverse sputter clean the surface to remove any surface oxide; apply a first coating layer using the PVD process to a maximum thickness; change the coating macro topology by polishing the coated surface; apply a second coating layer using the PVD process to a maximum thickness; and, grind or polish the coating to a desired dimension.
