How can you recognise that the electrolyte is used up?

Depletion is often indicated by slower deposition or a change in the color of the deposited metal layer. The original color of the electrolyte may also fade, or the brightness of the coating may diminish.

To keep the metal content constant, a suitable metal anode should always be used. This slowly dissolves during the process and enriches the electrolyte with the required metal ions. Over time, however, contamination occurs (foreign ions, organic residues, polymerization), and brighteners (if present) are consumed.

For this purpose, we offer brightener additives that specifically replenish the missing brighteners and other additives.

For electrolytes with insoluble anodes (e.g. gold), there is no automatic replenishment of metal.

Chromium electrolyte can also only be regenerated with great effort. However, since chromium is usually applied only as a thin top layer on nickel, this plays a minor role.
