Silver Tank Plating Solution – HS

Features Benefits
Designed to be used with our electrode ring fitted with silver electrodes. Plates fast – up to 0.6 microns per minute. This means you can build substantial thicknesses quickly.
No yellowing of deposit after rinsing. Greatly reduces the need for post plating polishing – particularly important if you’re plating very delicate or complexly shaped items.
The silver from the silver electrodes replenishes the silver plated out from the solution. Makes the Silver Tank Plating Solution – HS long life, which means you buy less solution in the long run.

To get the best out of the Silver Tank Plating Solution – HS you need to heat it to 50 degrees centigrade with moderate agitation. Immersing the plated item in water at 60-70 degrees centigrade for 1-2 mins immediately after plating greatly helps the solution’s anti-tarnish properties.

Silver Tank Plating HS Tank Calculator

How to use this calculator :

1. In the first box, enter the thickness that you want to plate to in microns (thousandths of a millimetre).

2. In the second box, enter the surface area of the article in square centimetres (cm2).

3. Click the ‘Calculate’ button.

4. Read off the amp setting for your rectifier, the plating time and the volume of replenisher to add before starting the plating sequence.

6. If you are using our Coulometer or MicroPlater, read off the coulombs or in the case of the MicroPlater, the amp-hours.

5. The weight of silver plated is shown in the final box.

Notes:

  • When silver beaker/tank plating on nickel, nickel-silver, brass and bronze, we recommend plating with NiPrep first before silver plating.
  • A gold strike is necessary when beaker/tank plating on stainless steel.
  • Plating rate can be increased to 1 micron/minute especially for articles with smooth edges.
    For higher plating speeds, an increase in agitation may be necessary. Refer
    to further note below.
  • Maximum thickness is around 10 microns.
  • Silver pH does not usually need adjusting as long as the silver anodes are kept in good condition and not allowed to run down.
  • A dull coating can indicate the current is too low. Increasing the current in roughly
    small increments can brighten the deposit. This solution is transparent and is
    possible to view the deposition process while plating.
  • Increasing the agitation too much can free particulate contamination from the
    anode bags giving rise to rough deposits.
  • Occasional carbon treatment may be necessary especially after being left idle
    for a period of months.
  • Brightness increases towards the lower end of the temperature range especially with
    solutions that have remained idle for extended periods of time and freshly carbon-treated
    solutions.

Fault

Possible cause

Corrective action
No plating at all.
 Electricity not flowing in the plating circuit indicated by a red light at the bottom of the display on the MultiPlater. Check all electrical contacts and clean if necessary.
No plating. Item looks damaged on removal from plating process.
 Leads connected wrongly. Check that the black connection from the MultiPlater is connected to the work piece and the red connection to the Beaker Ring.
Plating dull or matt
 Plating on to porous surface

 

 Polish the article you are trying to plate.
Lack of Silver Tank Brightener HS Add 1ml of Silver Tank Plating Brightener per litre of plating solution (to maximum 5ml per litre) until brightness is restored.
Temperature too low.

 

 Increase temperature to within operating range (see Tech Specs).
Low conductivity. Check the plating circuit for electrical faults.
Organic contamination. Treat with Carbon Powder (see shop).
Burnt deposit especially on corners and edges. Powdery in extreme cases
 Amp setting too high.

 

 Decrease the amp setting.
Article too close to the anode. Move the item in the beaker or rearrange the anodes.

 
Too little agitation. Increase agitation.

 
Temperature too low. Increase temperature to within operating range.
Incorrect estimation of surface area Recheck area calculation and use Silver Tank HS Calculator.
Plating but not to correct thickness.
 Incorrect amp or time settings. The vast majority of failures to plate to thickness are due to
wrong estimation of surface area. Double check your estimation of surface area
paying special attention to the units which should be in square centimetres.
Then input this together with your desired thickness into our online Silver Tank
HS Calculator.
Plating hazy solution turning a yellow shade
Silver electrodes worn beyond limit. Check electrodes and renew.
Deposit bright but rough.
 Particulate contamination especially in small installations without continuous filtration. Filter solution into a clean beaker/container or consider using
a filter pump intermittently or continually for convenience.
Pitting of deposit.
 Particulate matter in solution. Filter as outlined above.
Grease or oil contamination in solution. Treat with Carbon Powder as above.
Micropores on underlying surface. Cut back (linishing/grinding) and polish.
Un-plated areas.

 

 Improper cleaning. Check cleaning cycle especially for water breaks (see Online Manual)
Surface porous or deeply scratch brushed. Polish our the pores. It is not advisable to plate onto deeply
scratch-brushed surfaces due the the cavities at the bottom of the scratch
retaining contaminants such as oils and other debris.
Trying to plate a difficult-to-plate metal like stainless or
Inconel.		 Look under the Process Sequences tab for more information on
preparing different substrates.
Vertical tide marks especially evident on thin, flat articles when using a
stirrer for solution agitation.
 Coalescence of gas bubbles forming around the eddies produced
by the stirring action of the stirrer.		 Consider using a stirrer with reversing action in order to make
the agitation more turbulent. If only plating for a short period, consider
agitating the article by hand in a way as not to produce permanent eddies.
Plating blistering/bubbling up most commonly seen when plating on reactive
metals such as aluminium or zinc.
 Inclusions in basis metal which have trapped
acidic/alkaline components of the process solutions. The inclusions have been
plated over and the basis metal has reacted with the retained solution producing small amounts of hydrogen. Because this cannot escape it causes the plate to blister or bubble up.		 Abrade and/or polish out the inclusions. In some cases of deep
inclusions, you may risk distorting the profile of the article.
Deposit peels from basis metal.
In the case of multi-plated layers, check which layer is failing. This can be done a lot more easily if the base metal or plated layers are of different colour: for example, copper plated over brass then silver plated.
 Improper cleaning or surface preparation. Check the cleaning cycle for the metal.
Trying to plate a difficult-to-plate metal like stainless or Inconel. Look under the Process Sequences tab for more information on
preparing different substrates.
Plated a too thick layer of silver. Silver plated from Silver Tank Plating Solution HS is of low – medium stress. Plating much over 10 microns can result in stress cracking and in extreme cases, peeling. Reduce the thickness of silver plated. Consult our online Silver
Tank Plating Calculator for recommended amp and time settings for your work.

For best results, zinc needs to be mechanically finished prior to plating. This we advise polishing, linishing or very fine scratch brushing such as the finish obtained with fine Scotch-Brite™ mops. Attempting to plate on a course scratch brushed surface will result in poor adhesion and unplated areas.

More information about each process can found on the individual product pages.

Note: If the article is expected to be used out doors (for example, car parts), a protective copper layer of at least 10 microns should be plated after the alkaline copper stage. After copper plating, the article should be removed from the process and mechanically finished (polishing, linishing or fine scratch brushing) prior to silver plating.
