Abstract
The invention relates to an electrical contact element, an electrical contact arrangement and methods for manufacturing an electrical contact element and for reducing oxidization of a contact section of an electrical contact element. In order to avoid that the durability of the contact element and therefore of the contact arrangement is negatively influenced by growing oxide layers on contact surfaces, the contact element is provided with a cover layer with a chemical reducing agent that can be activated by frictional forces.
