Texturation au rouleau
Le service de texturation des rouleaux représente un processus de modification de la structure interne du matériau métallique ou de la structure de surface du matériau de la pièce (rouleau de travail des lignes de laminoir de finition) par des décharges électriques contrôlées où des impulsions électriques sont générées entre une électrode et un rouleau de travail, ce qui entraîne la formation de cratères microniques et de creux sur sa surface.
