Better use SS rod, it act as good counter electrode (SS 316)

U have to use even titanium substrate as counter electrode for the anodization process.. if u are doing in DC method their no problem when using Ag, SS, Graphite and Titanium. Bcs Counter electrode (cathode) will not affected in this process..

Dear Yasser

     Yes, you can use it.

best - you can use

Thank you all for you reply, But I am afraid that my electrolyte may react with it,

May I use these electrolytes: (0.15M NH4F + H2SO4) OR (1M H3PO4 + 0.3 wt% HF)

 Is there any comments on the usage of like these electrolytes with Ag electrode?

Thank you
