Rollentexturierung
Bei der Walzentexturierung handelt es sich um einen Vorgang zur Veränderung der inneren Struktur eines metallischen Werkstoffs oder der Oberflächenstruktur des Materials eines Werkstücks (Arbeitswalze aus Fertigwalzwerken) durch kontrollierte elektrische Entladungen, bei denen zwischen einer Elektrode und einer Arbeitswalze elektrische Impulse erzeugt werden, was zur Bildung von mikrofeinen Kratern und Vertiefungen auf der Oberfläche führt.
