  • 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.

  • DIRECT-CONTACT MEMBRANE ANODE FOR USE IN ELECTROLYSIS CELLS
    Publication number: 20130264215
    Abstract: The present invention relates to an anode system for conventional electrolysis cells, a process for the production thereof and its use for the deposition of electrolytic coatings. The anode system is characterized in that the anode (2) is in direct contact with a membrane (3) which completely separates the anode space from the cathode space. This anode system is therefore a direct-contact membrane anode.
