摘要:
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.

The present invention relates to an electrolyte and a process for depositing bronze alloys on consumer goods and industrial articles. The electrolyte of the invention comprises, in addition to the metals to be deposited and additives such as wetting agents, complexing agents and brighteners, in particular sulfur compounds which have a positive effect in the corresponding process for the deposition of the bronzes.
摘要:
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.
