Titanium anode for Surface finishing

In the field of the galvanic deposition of the metals for industrial or civil use, there are multiple possibilities of use for activated Titanium as anode, in replacement of the soluble anodes

Now for many years it’s been used as an auxiliary anode to stabilise the Nickel concentration in Watt or Sulfamate baths and in acid Copper plating baths.

The direct use, in replacement and with the same performances of platinised Titanium, a lot more expensive, in the baths of Gold plating, Platinum plating, Rhodium plating and Nickel/Palladium plating.

Also in the recent alloy deposition baths, for example of the Zinc/Nickel kind, activated Titanium is used exclusively.

In the modern decorative Chrome plating baths from Sulphates based trivalent Chromium, the use of this anode is mandatory, with a coating particularly designed to reduce to the minimum the formation of hexavalent Chromium which influences negatively on the performance and the quality of the Chromium deposited.

In the hard Chrome plating with hexavalent Chrome, activated Titanium is used in the cases when a particular anode geometry is required, which the classic anodes in Lead alloy cannot reproduce. But you need to take in consideration the combined use of Lead anodes to re-oxidate the undesired trivalent Chrome which forms on the cathode, in fact this reaction isn’t produced by the activated Titanium because of its low anode potential.

 

We can manufacture all types of coatings suitable for each process and it builds the anodes according to the client’s drawing or it proposes its own solutions. It can also activate anodes produced directly by the client.

Titanium anode for Electrogalvanising

This process is diffused in the iron and steel industry for the production of electrolytically zinc-plated iron coil, from a lightly acid Zinc sulphate solution.

The coil, with variable width ranging from around 600 to 1400 mm, quickly goes through a series of electrolytic cells under cathodic polarisation. Anodes can be in soluble Zinc, Lead or activated Titanium. The latter has considerable advantages compared with the others as it’s stable in size, lighter, non polluting towards the bath, it doesn’t require maintenance and compared to Lead it allows energy saving, thanks to its low overvoltage for the oxygen discharge.

Due though to frequent contacts between coil and anode, caused by the extreme proximity ( < 1 cm) which the process requires, short circuits arise which cause damages which compromise the performance and the duration of the coating.

We have developed a coating which is particularly resistant to this kind of strain with protective action on the titanium base which, following the local polarity inversions caused by the short circuits, loses the passivation and protective  TiO2 layer and tends to get corroded, with subsequent detachment of the coating layer.

This coating’s special formulation, with Iridium, Tantalum and Tin Oxide is particularly compact and it allows a very good separation of the Titanium base from the solution and therefore a barrier from the attack of the acids of the solution itself.

Titanium anode for Electrotinning

This process is similar to electrotinning for many aspects, in this case the material which is deposited is Tin.

 

In most plants the soluble tin anode is used, whereas the insoluble activated Titanium anode was inserted only in one or two cells, with the purpose of rebalancing the concentration of Tin in the solution, which has a tendency to increase the lower cathode efficiency compared to the anode’s.

In the last few years a system has been developed in which only insoluble anodes are used, whereas lead is dissolved separately in a dedicated dissolver.

Given the aggressiveness of the solution composed by methanesulfonic (MSA) and phenolsulfonic acid (PSA), which tend to increase the consumption speed of Iridium Oxide and furthermore the tendency to create some “overcoatings” of passivating Lead Oxide on the anodes, there was the need to design a particular coating’s formulation and a special treatment for the basic roughness which hindered the overcoating’s grip.

We can offer both coating solutions, both for the MSA and PSA cases.

Furthermore it builds the anodes according to the client’s drawing or it only supplies the re-coating service on worn-out anodes.
