Anodising Made Simple
« on: April 10, 2023, 05:43:57 pm »
I seen this video it may be of interest to you.
simple anodising with a battery or two or more.
distilled water
baking powder  - Borax
Acetone
anodization color with 9 volt batterys  see video.
9 18 27 36 45 54 63 72 81 90

Annoyingly simple anodising with a battery

see which voltages anodized

build a power supply that has a  voltage range for 24 to 90 at 1A
A standard 9V battery has about 400-600 mAh capacity

If I was using titanium bolts for projects saving money using a 9V battery to anodised them would be a little daft.

Yeah anodizing titanium hardware is fairly easy. You don't even need a tank you can just use aluminum foil, baking soda, and a paper towel to brush the color on.
The hard part is prepping a large smooth surface and getting that to look good. Or getting specific color shades to show up well.

Yes titanium bolts are expensive but custom color anodized ones more so, not sure what you are getting at here.

My point being that if I have just spent >10x the price of a normal bolt for a titanium one I am not going to finish off that expense by using a cheap solution to have them anodised.

I have titanium bolts in the shed, I even have the drilled ones for racing and I have yet to find a use for them as they are not somthing you use for the fun of it.

I may have overestimated the use of expensive titanium as in contrast to the way cheap aluminum is widely used in
electronics enclosures and fasteners.  as the video thumbnail had suggested.
as for the use of 9 volt batteries shown in the video. a lab power supply is the best for electroplating.
a lesson to myself, do lots of research before posting anything.  :-[
titanium vs cheap aluminum. video thumbnails can be misleading. :palm:

Cheap or expensive anodizing doesn't really matter for Ti, its just for the color.
You can probably use 316 stainless bolts in most applications requiring corrosion resistance (salt spray), but in some cases its just too soft and weak vs Ti.

Caswell Plating sells kits for all kinds of metal plating and anodizing procedures, and publishes handbooks that lay out every aspect of these processes.
