  • WEAR AND CORROSION RESISTANT COATING
    Publication number: 20090053486
    Abstract: A method for treating a substrate (such as the gears of a gear set) to provide the substrate with both wear protection and corrosion resistance is disclosed. The method comprises providing the substrate with a wear protection layer and providing corrosion resistant layer. The wear protection layer can be applied to the gear and then the corrosion resistant layer can be applied over the wear resistant layer. Alternatively, the corrosion resistant lay can be provided and then the wear resistant layer can be formed over the corrosion resistant layer.

  • Differential with thin film coating at cross shaft and processes for manufacturing the same
    Patent number: 7300379
    Abstract: A process for improving the durability of a differential, where the differential has a pinion shaft and a pinion, the pinion shaft having a surface that contacts the surface of the inner diameter of the pinion. The process comprises bonding to the surface of the pinion shaft or the pinion or both, in the region of the interface between the pinion shaft and pinion, a coating having both a lower coefficient of friction and higher seizure resistance than that of the substance of the pinion shaft when in contact with the substance of the pinion.

  • Coated rolling element bearing cages
    Patent number: 6994475
    Abstract: A rolling element bearing comprises an inner ring (3) and an outer ring (2) each provided with a raceway (4, 5), said rings having land regions (10, 11) on opposite sides of their raceways, and a series of rolling elements (6) which are in rolling contact with the raceways and which are mutually spaced by a cage (7), said cage (7) engaging the land regions (10, 11) of said ring, said cage (7) being coated with a wear and friction reducing coating over its full surface.
