  • ELECTROLYTE AND ITS USE FOR THE DEPOSITION OF BLACK RUTHENIUM COATINGS AND COATINGS OBTAINED IN THIS WAY
    Publication number: 20140131209
    Abstract: The invention relates to a ruthenium electrolyte which is suitable for the deposition of decorative and industrial layers having a particular blackness. The invention further relates to the use of the electrolyte of the invention in a process for the deposition of decorative and industrial layers of ruthenium having a particular blackness (“black ruthenium) on jewelry, decorative goods, consumer goods and industrial articles. The invention therefore likewise relates to corresponding layers and the articles coated in this way. The electrolyte is characterized in that it operates in the weakly acidic to alkaline pH range.

  • PROCESS FOR THE DEPOSITION OF PLATINUM-RHODIUM LAYERS HAVING IMPROVED WHITENESS
    Publication number: 20110308959
    Abstract: The present invention relates to an electrochemical process for the deposition of coatings comprising an alloy of platinum and rhodium on, in particular, decorative articles. The process of the invention is characterized in that defined conditions are employed under which the electrolytically deposited layer has, contrary to expectations, a high whiteness which comes extraordinarily close to the appearance of silver.
