Abstract

La présente invention concerne la gravure électrochimique qui permet de façonner la topographie d'un métal ou d'un alliage nanocristallin ou amorphe, laquelle peut être produite par tout procédé incluant un dépôt électrochimique. Des procédés de gravure courants peuvent être utilisés. La topographie peut être régulée par des paramètres variables qui produisent l'élément et/ou les paramètres de gravure. L'article nanocristallin présente une surface comprenant au moins deux éléments, au moins l'un d'eux étant un métal, et l'un d'eux étant plus actif sur le plan électrochimique que les autres. L'élément actif a une distribution spatiale définie dans la pièce à travailler, qui est en rapport spatial prédécesseur avec la topographie spécifiée. La gravure élimine préférentiellement une partie de l'élément actif, de façon à obtenir la topographie spécifiée. Une régulation est possible en ce qui concerne : la rugosité, la couleur, en particulier dans un spectre allant de l'argent au noir en passant par le gris, la réflectivité et la présence, la distribution et la densité du nombre de creux et de canaux, ainsi que leur profondeur, largeur, dimension. Des paramètres de traitement qui ont été corrélés dans le système Ni-W aux caractéristiques topographiques incluent, tant pour la phase de dépôt que pour la phase de gravure d'une surface nanocristalline : le cycle de service, la densité du courant, la durée de dépôt, la chimie du dépôt, le rapport de polarité. L'influence relative des paramètres de traitement peut être notée et corrélée pour établir un rapport entre les valeurs des paramètres de traitement et le degré des caractéristiques topographiques. Une régulation peut être établie en ce qui concerne les caractéristiques topographiques. Une corrélation peut être réalisée pour tout système qui présente une distribution spatiale définie d'un élément actif qui est en rapport spatial prédécesseur avec une caractéristique topographique souhaitée.
