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.

Claims

AMENDED CLAIMS received by the International Bureau on 11 April 2013 (11.04.2013) Amendments according to Art. 19 PCT Claims
Anode system which is configured in such a way that it is suitable for use in electroplating cells for the deposition of electrolytic coatings as a result of simple dipping into the catholyte, wherein, after dipping into the catholyte, the catholyte is separated from the anode by a swollen polymer membrane which is permeable to cations or anions and the polymer membrane is in direct contact with the anode and not with the cathode,
characterized in that
the membrane is fixed onto the anode by means of electrolyte-permeable holders and pressing devices by means of a multilayer structure, which ensures good contact of the membrane with the anode.
Anode system according to Claim 1 ,
characterized in that
the anode consists of flat material, sintered material or expanded metal.
Anode system according to Claim 1 and/or 2,
characterized in that
the anode is selected from the group consisting of platinised titanium, graphite, stainless steel, titanium coated with iridium-transition metal mixed oxide, tantalum or niobium sheets coated with mixed oxides and special carbon material ("Diamond Like Carbon" DLC, "glassy carbon" GC) and combinations of these materials.
Anode system according to one or more of the preceding claims,
characterized in that
a membrane selected from the group consisting of polypyrrole membranes, olefin polymer membranes, sulphonated polystyrene membranes,

perfluorophosphonate membranes is used as polymer membrane.
Process for producing an anode system according to one or more of the preceding claims,
characterized in that
i) the membrane is allowed to preswell in deionized water,
ii) the preswollen polymer membrane is applied directly to the anode,
iii) the membrane is fixed onto the anode by means of electrolyte-permeable holders and pressing devices by means of a multilayer structure, which ensures good contact of the membrane with the anode, and
iv) the anode is enclosed in the polymer membrane so that it cannot be wetted by the catholyte.
Use of the anode system according to one or more of Claims 1 - 4 for the electrochemical deposition of metal coatings on decorative and industrial articles.
Use according to Claim 6,
characterized in that
the decorative and industrial articles are dipped into the appropriate catholyte and a sufficient flow of current between these and the anode for deposition of the metal coatings is brought about.
Use according to Claim 6 and/or 7,
characterized in that
the deposition is carried out in a temperature range of 1 - 150°C.
Use according to one or more of Claims 6 - 8,
characterized in that
a catholyte capable of depositing metals or metal alloys selected from the group consisting of silver, gold, palladium, platinum, rhodium, ruthenium, iridum, rhenium, copper, tin, zinc, iron, nickel, cobalt, chromium, manganese, molybdenum, tungsten, tantalum, thallium, bismuth, antimony, indium, gallium, lead, cerium, selenium, cadmium, samarium, vanadium, tellurium and alloys thereof is selected as catholyte.
10. Electrolysis cell comprising a cathode, a catholyte and an anode system according to one or more of Claims 1 to 4 for the deposition of electrolytic coatings.
