I was reading earlier today that Titanium can be anodized using coke and 9v batteries.....only thing i had made of titanium was my oem gear ****....well i had to have a try for myself.



what you need is a non metallic container (mug) put a folded bit of aluminium foil down one side of the mug, connected a wire for the negative (note in my pic i have the red and black leads the wrong way round GEARKNOB GOES TO BATTERY POSITIVE, FOIL GOES TO NEGATIVE). i attached my gearknob to a bolt and hung it into the coke (i used diet but i dont think it matters) THE GEARKNOB AND FOIL MUST NOT TOUCH.

the best way to do it is get your gearknob hanging in the coke and make sure theyre not touching before you connect the battery (batteries).

For my first attempt i used two batteries for 18v and got the results below after about 1 minute, a bit blotchy and not really the colour i was looking for.



so i added another battery and put it back in for another minute..... getting more like it now



i then started trying again, adding more and more batteries, but it just started going a bit grey. i sanded it down with a bit of wet and dry in a drill (took about 30 secs) and tryed a few more times. to get it looking like below i had 7 batteries connected together (63v, i think voltages upto 150v are used) and connected the power for about 3 secs, span it round 180 degrees and gave it another 3 secs.this was because i found the side nearest the foil changes colour a lot more quickly.






The idea is that different colours can be gained by using different voltages, but you would usually have an adjustable power supply and better solutions than coke to get a broad spectrum of repeatable colouring. even so, just with the batteries and coke, i'm sure you can get good results by experimenting a bit........there's a lot more info out there on this, i have barely touched the surface.

if you like, have a try, and get some pics up :D

 

damnn nice shiet man.. ill prob give it a try :D

 

Haha. High school chemistry put to use. An electrochemical cell...

 

very cool!

 

light blue/greenish with red removed.

i have now found if you put the foil all the way round you get a much more even coating aswell

 

haha cool ish

 

i think i might be too bored, i'm gonna have to pick a color and stop myself

 

Cool. I bet you have fun dying easter eggs Maybe you should figure out how to make each color and make a chart and make this a COMPLETE DIY. Cool stuff!

 

there are charts available but to be honest everyone seems to get different results depending on how they do it and how flat the batteries are etc......for anyone having a go once your set up its easy to experiment for yourself

 

While the science behind it is cool, am I the only one that thinks that rainbow colored shift ***** are kinda silly looking?

 

yeah i'm not leaving it stripy like that, just thought it would show the colours i've managed to get off a little better

 

VERY cool.

 

is the type R shifter Titanium? I have one I got off ebay not sure if its titanium or not...

 

well now you have an easy way to test if it is genuine or not, oem is titanium

 

Very interesting. I support Tyrant's idea for an complete DIY.

 

The non-USDM/CDM ones are. USDM/CDM are aluminum (or as the Brits like to say aluminium).

 

I saw this done a while back with radiator hose clamps. good info

 

sorry, didnt realise US didnt get titanium shift *****.

Wasnt trying to rub your noses in it or anything like that ...........honest

 

Lye (Drano or Easy Off oven cleaner) takes the anodizing off aluminum. Dunno if it works with Ti.

 

yeah i think it works on Ti too

 

DRINK THE COKE AFTERWARDS....IT ***** YOU UP....

 

People use Coke to unclog drains instead of using Drano.

 

People also use Coke as a spermicidal douche. Have been since some window licker decided it worked for her the 1950s. Doesn't mean it actually works, nor does it have any bearing on the product as per what it is intended (consumption).

...on that note, did you know that tap water can dissolve solid steel?!?

 

Cool idea OP.

 

BTW, anyone have any idea how long that will last?
