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 process for producing a contact plug includes: providing a blank made of a lead-free brass alloy; semihot forming a first section of the blank to form a crimping region, the crimping region having an opening for insertion of a conductor end and the first section of the blank being heated to a semihot forming temperature before and/or during the semihot forming; and cold forming a second section of the blank to form a plugging region, the plugging region having a plurality of lamellae.

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.
