In Niobium & Titanium
Hi there. I have been experimenting with anodising titanium for a little while, along with a friend. We have different set-ups, and I am following the technique outlined by Bille Seeley (SMT, TSP, etc). My friend uses sulphuric acid in place of TSP, which is something I do not want to do. His colours come out clean and pure (no mottles etc). Mine, on the other hand take forever to change, even at lower voltage, and have an effect that I can only describe as like a translucent white veil over them.. The preparation and cleaning is identical - I have prepared pieces for my friend in helping him with a collection. Any clues?

I am using the SMT unit and the set-up / technique as generally described by Bill Seeley. Sometimes, I see small sparks coming off the work piece at the higher voltages. What do these signal, and should I be worried? Thanks in advance, Oz
