Titanium anode basket passivation

+++++

We are currently using SnPb plating and Pure tin matte finish chemistry and our machines are meco EDF+EPL 2400's strip to strip. Can you please explain to us how the titanium basket become passivated? Is this also similar to the passivation of anode balls? How do you activate it if it is passivated?what will be its impact on the plating solution and its implication on the finish product?

Thanks!

I don't believe that this is any problem at all, Michael. The anode basket does become passivated with a thin coating of titanium oxides due to its having a positive charge on it, but these should not interfere with it carrying the current to the anodes that are in it. I have never heard of activating a passivated anode basket.
