I have made myself a good anodiser, with a good amp control, but I
have not found the best anodising solution for titanium.
Reactive metals speak about Tri Sodium Phosphate (Na3PO4) but this
is in the Netherlands not available, even not at the chemical
suppliers. It seem to be completely banned here. I have tried Sodium
Tio Phosphate (Na5P3O10), but the colours will not be very bright and
are fading if the object is longer in the solution at lower voltages.
It seem to be etching the titanium. Now there are subscriptions who
say Ammonium sulphate, Sulphuric acid solutions ect. can be used.
My question is who has experimented with several different chemicals
or mixtures and can advise me a good solution.
Thanks in advance
