rhodium bath
Rhodium Bath Rhoduna PT ONE
The rhodium concentrate is used for the decorative surface coating of e.g. jewellery, watches and spectacle frames. It produces a white, high-gloss, extremely abrasion-resistant deposit.
The rhodium bath is used in a conventional electroplating unit. The free acid content is 22 g/l for a new bath. It increases during the service life and with repeated regeneration. This reduces the deposition rate, but this can be compensated by extending the exposure time.
Technical data:
Rhodium content 0.3 g/l
Platinum content 0.7 g/l
Temperature 40 - 50°C (optimum 45°C)
Coating time 2 - 4 minutes
Voltage 2.5 volts (for Pt/Ti anodes)
Current density 3 A/dm2 (2 - 5 A/dm2)
Deposition 3.5 mg/Amin
pH < 1
Movement Electrolyte or product movement
Anodes Titanium, platinised
Tank material Glass, acid res. Plastic (PP, PVC, etc.)
Layer thickness approx. 0.3 µm
Hardness approx. 600 HV
