Anodizing titanium

[Sunny124]

Is there any site that has a accurate color chart for Anodizing titanium? Or is it different for each knife handles you Anodize? Thanks

Colour hinges on voltage and other variables. If you're hoping to home brew a specific hue on your first try it's going to be tough to hit it.

There's a chart at this "how to" http://www.instructables.com/id/Anodize-Titanium/

I've found this one to be usable and accurate:

I have found that it completely depends on the size of the piece being anodized. Take it very slow, pull out the piece and dry it before deciding. The color can change dramatically when dry!

ok sounds good ill try that once i get my supply.

^^& The chart above reflect colors achieved after etching the piece (Usually with Multi Etch). Without that surface prep you will get colors that are a bit duller, and will need voltages slightly higher to get there. That being said, Whitty makes a good point...there are a lot of factors such as:

How did you prep your part
whats the surface finish
did you etch
what electrolyte are you using (and how strong or diluted is it)
size of piece being anodized (as well as size of negative cathode)

once you get your supply, you are going to have to play around a bit

Alright and can i use anything else like etch but not exaclty that? And where can i get multi-etch? thanks

i use eagle one mag wheel (etching) cleaner from the parts place works well and i dont have to orderr it in

Oh shit alright haha way easier thanks.

A accurate chart for the colors you get when anodising does not exist. It depends on a lot of factors:

Cleaning,
Etching,
anodising setup,
Electrolyt solution,

Etching titanium makes a big difference. You will get deeper and brighter colors.
I am etching my titanium parts with Super-etch. It's a clone of multi-etch I think (nmulti-etch isn't available here in europe)
I have tried HF etching, it works great, but I stopped using it after I heard about fatal accidents when using the stuff.


edit: you can get super-etch here : http://www.biketweaks.com/titanium-etching
