Ball pivot with a surface coating against corrosion, useful in wheel suspension or steering of motor vehicle, comprises a ball joint and a barrel, where the ball pivot is scaled in axial direction viewed in zones

摘要

The ball pivot with a surface coating against corrosion, comprises a ball joint (12) and a barrel (14), where the ball pivot is scaled in axial direction viewed in zones (24, 26, 28, 30, 32), which are equipped with a surface coating coordinated in its load. The surface coatings of the zones are aligned on the mechanical load of the zone, have different hardness and are applied by a thermal spraying method or cold gas spraying method. An independent claim is included for a method for the production of a ball pivot.
