Title (EN) A PROCESS OF GALVANIC DEPOSITION FOR OBTAINING COLOURED RUTHENIUM DEPOSITS AND/OR OF ITS ALLOYS
(FR) PROCÉDÉ DE DÉPÔT GALVANIQUE PERMETTANT DE FORMER DES DÉPÔTS DE RUTHÉNIUM COLORÉS ET/OU DE SES ALLIAGES
Abstract:
(EN) The present invention refers to a galvanic deposition process for obtaining the deposit of ruthenium and/or of its alloys, on an object in order to obtain final ruthenium layers with particular colorations, otherwise not obtainable with traditional electro-deposited deposits. The deposits obtained in this way can be used as a decorative finishing layer, or they can be undergone to a further "re-uncoating" treatment, such as with abrasive ceramic materials, in order to obtain "un-coated" finishing "of vintage type".
(FR) La présente invention concerne un procédé de dépôt galvanique permettant de former un dépôt de ruthénium et/ou de ses alliages sur un objet afin d'obtenir des couches finales de ruthénium ayant des colorations particulières, qui sinon ne pourraient pas être obtenues avec des dépôts réalisés par électrodéposition classique. Les dépôts ainsi obtenus peuvent être utilisés comme couche de finition décorative, ou ils peuvent être soumis à un traitement ultérieur de "ré-élimination de revêtement", par exemple à l'aide de matériaux céramiques abrasifs, pour obtenir une finition "à nu" "de type vintage".
