Abstract: A method for producing a contact element formed at least in sections from a brass alloy, and a contact element formed at least in sections from a brass alloy. In a method for producing a contact element formed at least in sections from a brass alloy, which method permits both productive and economic production of a contact element from lead-free brass alloys at least in some sections by shaping, more particularly by machining methods, and the process-safe contacting by crimping, for example of plug contacts, a blank for the contact element is first provided. Subsequently the structural state of the blank is changed by a first thermal treatment to increase the ß phase content, after which the contact element is formed from the blank with a higher ß phase content. The structural state of the contact element formed is then modified by a second thermal treatment to increase the ? phase content.

Abstract: A method for producing a zinc coating optimized for coefficient of friction on a steel component. In order to provide such a method resulting in a coating having good corrosion protection properties, good adhesion and a stable, constantly low coefficient of friction, including in the case of repeated use of the steel component, in particular multiple draft, wherein the method can be carried out both easily and cost-effectively, a zinc coating is first applied to the surface of the steel component by a galvanic deposition process and subsequently a heat treatment is carried out at a temperature of below 420° C. for the specific forming of intermetallic zinc-iron phases in the galvanically deposited zinc layer in order to optimize the coefficient of friction of the steel component.

Abstract: Bicycle frame formed by a half-shell (1) made of a thermoplastic material. The half-shell (1) is fiber-reinforced at least in regions, and includes a cover element (2), which is, at least in regions, connected to the half-shell and preferably closes the half-shell.
