Abstract

La présente invention concerne des surfaces texturées qui comprennent des rugosités déposées de façon électrochimique sur un substrat et qui sont préparées par un processus de courant direct pulsé. Les substrats représentatifs sont des éléments de machine tels que des rouleaux de machine. On fabrique selon cette invention des surfaces texturées améliorées en commandant la densité, l'uniformité et la taille des rugosités par un processus de courant direct pulsé. Ainsi, on prédétermine les caractéristiques de rugosité en sélectionnant une forme d'impulsion possédant une densité de courant spécifique et des paramètres d'intervalle d'impulsion ainsi qu'un temps de dépôt total durant lequel des rugosités aux caractéristiques recherchées seront déposées sur le substrat.
