Ti - arcing bath of TSP
The peice: 1"x2"x1/4" 6AL/4V. Prepped with 'Multi-Etch' from Reative
studios. The power source - mini anodizer also from Reactive. Cathode is stainless foil (supplied with anodizer) I started with TSP at 3% and tried all the way up to 25% mixed with water (not tap but from a 'glacier' reverse osmosis filter - the ones you get drinking water from) I wanted the higher voltage colors - but as soon as I put them in the bath, arcing occurs actually on the surface of the peice. The arcing is in many places at once and of course ruins the color with the brown/gray surface where arcing occurs. The bath doesn't heat up, the cathode isn't touching, it is just arcing all over even with the current limiting device on and set to 0.1 Amps. As soon as it gets to 70 or 80 volts the arcing starts - along with the bubbling of the electrolyte (just at the surface of the peice) it would be quite beautiful to watch these 'mini-stars' appear on the titaninum under the surface - that is, if it didn't ruin the color. I know the arcing is cased by the breaking down of the electrolyte - but that should only happen with heat. The TSP should not be breaking down with a 0.1 Amp setting and a big chunk of Ti like that should it? I could understand if this were a brush application but it is submerged (just the peice and a Ti hook - not the anode) in a 1/2 litre of elecrolyte. Any suggestions? Is there an alternative to TSP that doesn't break down so easily at high voltage (not anything nasty that I can't handle with rubber gloves please) Thanks |
