The present invention is directed toward a platinum electrolyte which contains certain additives, and to a method for the electrolytic deposition of a platinum layer with the aid of the electrolyte according to the invention.

Platinum electrolyte

The present invention relates to an electrolyte and to a method for the electrolytic deposition of silver coatings and silver alloy coatings. The electrolyte according to the invention is cyanide-free, storage-stable and ensures the deposition of high-gloss, brilliant and white silver and silver alloy layers for technical and decorative applications.

Electrolyte for the cyanide-free deposition of silver

The present invention relates to an electrolyte and to a method for the electrolytic deposition of silver-rich silver-palladium alloys which to a minor degree also include selenium and/or tellurium. The electrolyte of the invention allows uniform deposition of such an alloy on conductive surfaces across a wide range of current densities.

Electrolyte for the electrolytic deposition of silver-palladium alloys and method for deposition thereof

The present invention relates to an electrolyte for the electrochemical deposition of palladium or palladium alloys on metallic or conductive substrates. The invention likewise relates to a corresponding electroplating process using this electrolyte and specific palladium salts which can be advantageously used in this process.

Pd and Pd-Ni electrolyte baths

The present invention relates to a process for preparing palladium complexes. In particular, the present invention relates to a process in which ammoniacal complexes of palladium (hydrogen)carbonate are converted into complexes with oligoamine ligands.

Process for preparing complexes of palladium (hydrogen)carbonate with amine ligands

The invention concerns a bath for the electrochemical deposition of high-gloss white rhodium coatings and a whitening agent for the same. The brightness or degree of whiteness of the deposited coatings is significantly increased by means of compounds having the formula R&#x2014;SO&#x2014;H, wherein m is the numbers 3 or 4 and R is a straight-chain or branched chain or cyclic alkyl group having up to 20 C atoms, as a whitening agent. The thickness of the coating that can be deposited without a bloom is also significantly increased.
