摘要: A ball joint with a ball pin and a steel ball pin with a joint ball. The ball joint and ball pin are suitable for use when, for example, solid-on-solid friction predominates under high static pre-loading or high operational loads and with small joint movements. A portion of the surface of the ball pin has surface layer hardening in order to increase a fatigue strength of the ball pin. The ball pin and the ball joint, on portion of the ball pin without the any surface layer hardened, includes a nitrided layer as wear protection. The ball pin and the ball joint provide an advantageous combination of high fatigue strength, good corrosion protection and high wear-resistance. The nitrided layer of ball joints, previously only regarded as improving corrosion protection, also functions as a wear protection. Thus, these ball pins overcome the mutual exclusion between surface layer hardening and nitriding.
