r plating bath.
The materials should be leached in hot water (43 to 71 C, 110 to 160 F) with changes of water until fresh leach water no longer foams. The initial leach can be augmented by the addition of 3% sulfuric acid.
The anode current density should be maintained between 10 and 30 ASF (0.93 to 2.8 ASD) in general operation. Excessive anode current density can lead to anode polarization and poor deposit distribution and structure.
Anode to cathode distance spacing is also important in th
