So ! I heat anodized a titanium CRKT M16 to a deep purple. If I want a two tone colour using electricity ( 9 volt batteries ) what would be the best result. Can I get light blues or is that voltage already "coated over".

What is the electricity equivalent of purple on the heat ? Has anyone tested this ? If I dont get any replies Ill post the results, I only have 6 batteries so my maximum voltage is 54 :grumpy:

Pimpers share your notes !


You can post your anodizing jobs too, love to see good ones :)
 
From my limited understanding, I believe heat induced oxidation produces colors comparable to the lower half (ish) spectrum of colors produced by electro anodizing. IIRC, I got purples around the 15-20 volt range, and transitioned into blues with lighter blue coming around 30-35 volts. I seem to remember the voltage/color mix to be slightly different with CP Ti than 6Al4V. Keep in mind that alkaline battery voltages diminish quickly at first, then settle into a slow but steady drop, then begin to fall quickly again. If possible, I would check the voltage of your system before applying it. Here's a general idea of the colors you could expect in different voltage ranges:

I'm very interested to see your results!

I've never tried to electro over heat ano so I'd be interested to know how that goes.
You can get all these colours with heat but it might knacker the Ti


I do a bit of electro.

How did you do that? It looks cush

The bottom one is electrochemical anodising :)
