Title
(DE) KONTAKTSTELLE FÜR EINEN ELEKTRISCHEN KONTAKT
(EN) CONTACT POINT FOR AN ELECTRICAL CONTACT
(FR) ZONE DE CONTACT POUR UN CONTACT ELECTRIQUE
Abstract
(DE)
Kontaktstelle für einen elektrischen Kontakt, bestehend aus oder umfassend einen Verbund, umfassend ein Metallsubstrat und auf dem Substrat angeordnet eine plasmapolymere Schicht und eine metallische Deckschicht, wobei zwischen der metallischen Deckschicht und der plasmapolymeren Schicht eine Mischschicht vorhanden ist, die hinsichtlich ihrer stofflichen Zusammensetzung einen Gradienten von der Zusammensetzung der plasmapolymeren Schicht hin zu der Zusammensetzung der Deckschicht aufweist.
(EN)
The invention relates to a contact point for an electrical contact, consisting of or comprising a composite, comprising a metal substrate and a plasma polymer layer arranged on the substrate, and a metal cover layer. Between the metal cover layer and the plasma polymer layer, a mixed layer is present, which, with respect to the material composition of the mixed layer, has a gradient from the composition of the plasma polymer layer toward the composition of the cover layer.
(FR)
L'invention concerne une zone de contact pour un contact électrique, composée d'un composite ou comportant un composite, comprenant un substrat métallique, une couche polymère plasma disposée sur le substrat et une couche de couverture métallique, une couche mixte étant présente entre la couche de couverture métallique et la couche polymère plasma, qui en ce qui concerne sa composition de matière, présente un gradient de la composition de la couche polymère plasma à la composition de la couche de couverture.
