Abstract:
A hard, wear resistant and ice-phobic coating (10) can be applied to an air foil surface (12) in a single application to enhance the deicing of the surface. The coating includes a functional top layer (14) which is harder than the air foil surface and has high contact angle with water. The functional layer contains carbon (>35 atomic%) and hydrogen (0-40 atomic%) in a diamond-like carbon, glassy, or amorphous configuration, as well as incorporated silicon and oxygen (0.1-40 atomic% each).
Abstract:
A bearing which has a longer useful life in mild aqueous corrosion conditions comprising rolling elements and raceways with the rolling elements coated with a thin nanocomposite (NC) coating which has higher surface hardness than, is chemically incompatible, with and has low solubility relative to the raceway surfaces. The bearing is corrosion-tolerant rather than corrosion avoidant and functions by reducing the effect that corrosion has on bearing life by preventing adhesive wear and minimizing the effect of debris damage on bearing life caused by micropits, etch marks and rust formation on the raceways.
Abstract:
A bearing assembly having an inner race ring (14) that defines an inner raceway and an outer race ring that defines an outer raceway on which the plurality of rolling elements (22) roll. The bearing raceways are machined using surface finishing operations to create preferred surface profiles and textures for improving lubrication performance. The profile of the raceway is initially created using a first grinding process to form a rough surface profile including a rough central band (34) and rough recessed side bands (38). A second grinding process is used to smooth the central band. This raceway surface profile increases lubrication performance.
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.
