Titanium Inodizing - Gold easy and Pink problem

[CoolHandLuke]

saw one paper that used 10% Potassium Hydroxide, got Pink colours at 50vdc

so a few bits of chlorine and minerals i doubt have much impact.

I quit drinking water at the lab because the odor of chlorine is sickening, I had to get bottled water to get any hydration

Switch to beer, problem solved...

Drink beer at work? This aint Canada eh?

I am using this TSP-PF Green Box which come in the Anodizer kit, is that what you guys are recommending?

Thought I would post a pic of one I did, the pink turned out well. Dual color with borox solution.

so what voltage was this? 72v?

 

[Affinity]

for the pink.. maybe around 75

I just got my anodizing kit in last week, the same one as renato (from painful pleasures). How long seconds, minutes, do you anodize for?

It literally takes a couple of seconds. I rubber wheel the abutment, polish it, and then steam clean it before anodizing. This creates a much more vibrant gold color.

Thank you, Brett. If you leave it in a little longer, does it get a deeper anodize color, or once it's done, it's done?

I do have some abutments that I can experiment with, but I do appreciate any replies and help

once its done, its done. important to note however, this is not like a radio you cant dial it back. if you go too far youll have to trim it off and start again. so go UP slowly in voltage.

This is creating a spiffy form of 'rust' on the outer molecular layer. All exposed titanium will be effected. After it's done, it's done. Longer exposure will do nothing without a voltage change.

Thank you both for your helpful replies, I appreciate it

I got this off of Reddit. The OP didn't put any times down so there's still that to deal with, but these look pretty good

The time doesnt matter, it will only anodize to the voltage then it stops.. generally, you can potentially do it too long, and it appears brownish or burnt, but it only takes a matter of 3-4 seconds to get that color..

also, the instructions say that for colors higher than 75v you need to make sure the probe is sanded and clean

I believe adding baking soda to tsp also helps in getting better colors.

I polish my abutments before I annodize them. Produces a more vibrant gold.

I'm thinking of getting an anodizer and thought this was an interesting bit of info. Seems to have jump-started the thread. I can always use more feedback

Dude! Doug!! Get an annodizer! lol

We spent $300 on a micro annodizer. It takes about 5 minutes to prepare and annodize an abutment. You can charge more for a gold hued titanium abutment. You will have the annodizer paid for after about 10 abutments. I have been trying to get away from doing zirconia abutments whenever possible. A layered zirconia crown will mask a gold hued abutment in the vast majority of cases. The gold hued abutment won't discolor the tissue like a silver abutment will. For emax cases, we still lean towards zirconia abuments unless the shade is darker and i can make the emax core very thick.
