Anodizing titanium
« on: March 18, 2008, 11:45:36 AM »
This magazine article sort of explains it...
http://www.theodoregray.com/PeriodicTable/PopularScience/2005/08/1/
This guide is good to follow for power/voltage vs color...
http://www.valhallaarms.com/wyvern/titanium/images/ti_color_large.jpg

Stuff you'll need...
-water/baking soda solution, or other electrolyte like some sodas
-power adapter/electrical cord and alligator/roach clips
-cotton balls, paper towel, or anything really that soaks up water and won't effect the electricity too much
-something made of titanium



--Mix the water and baking soda in something non-conductive.
--Cut/strip the wires coming out of the power adapter you're using.
--Clip the positive wire to whatever you're working on, and clip the negative to a cotton ball or whatever you're using for a 'brush'
--Cover the area you want to work on first with the solution, also soak the 'brush'
--plug in the adapter
--"paint'

This was with a 31v printer adapter. If I left it in one spot it would end up sort of a light blue, but if you only leave it on for a short time it'll go goldish-purple-darkblue-and so on. I sanded/redid it a bunch of times, and I know it looks pretty crappy. Use the link above to figure out what voltage you'll want.








This one (friends bike) was with a normal cord just cut and plugged into an outlet, so probably around 120v. I got shocked a bunch of times and had to flip circuits a few times, but I'm not dead.





It's almost an optical illusion, like it'll change colors with the angle you're looking at it from or the lighting, but it is 'permanent' unless you sand it off.

I had it in my hands with the 31v, and it was sitting in the water with the 120. As long as the metal of both clips doesn't touch the titanium at the same time it won't spark.

Also, don't put the wires in your mouth or near an open gas tank.

I'd be scared I'd electrocute myself messing around with that much V like that, especially from a 120V socket.  It looks awesome, though. 
being small has it's advantages... :mellow:

Forgot about this...





Did this one a little differently...


I wound a brake cable around the inside of a bucket, and connected one end to one side of the electric cord.
Then I put the sprocket in the center so it wasn't touching the brake cable at all, or close enough to arc, and then connected the other end of the wire to it.
Added the water/baking soda, and plugged the electric cord - an old, cut extension cord - and then unplugged it after a few seconds of fizzing...






I really want to see someone do this with bigger parts ...





















too much
