Anodising PPP-106 stuff

Random anodising! - Or anodizing if you are American! The Engineered By Design Anodising process. This video shows the blue dyeing phase, with a tank heater & agitator in the tank. The full details can be found on the ppp-106 webpage here: www.ppp-106.co.uk. This video does not show the acid tank & water wash & steam / boiling water sealing process.

The Process:

You use Lead as the -VE connection & the item you want anodised is the +VE connection. Then you pass a current through the tank, (DC at 12V - so you could even use a car battery) - This will form a clear, but porous layer, on the aluminium being anodised. After this process you can then dye the item in a heated tank of dye, before the final process of sealing in steam / boiling water.

I read about the process and I'm still a little confused. Do you literally use lead metal as the -VE connection? How long should I leave the parts in the tank with the current? Also, what can I use to make sulfuric acid? Can I use drain cleaners like Drano? And how much should i use in a 5 gallon bucket?

@DrOhcysp Hi There, where to start? - The process of Anodising is relatively simple. Yes you want a lead sheet to act as the Cathode, - You want to make sure there is no steel in there anywhere (as the sulphuric acid would eat it up!), there are online calculators to work out the amount of time required to leave it in the tank, this is based on the surface area of the part you want to anodise and the voltage/current that your power source puts out....

And, NO.... You CANNOT use Drano!!!!!! :)

I ride mountain bikes and dirt bikes, and I would like to anodise some parts lol. Could you please tell me the process of how to do that. I have been reading your responses and I kind of get it. It would be cool if I could use food dye, Thanks.

Well pretty much the method I have written in presvious responses stands!

You use Lead as the -VE connection & the item you want anodised is the +VE connection. Then you pass a current through the tank, which will form a clear, but porous layer, on the aluminium being anodised. After this process you can then dye the item in a heated tank of dye, before the final process of sealing in steam / boiling water.

how come if i put the negative on the lead and the posotive on the piece im doing nothing happens, but if i swap them over the peace then starts fizzing and it works well,

cheers mick

Hi Mick,

Hmmm, I would ask if you are totally sure. The whole concept of "Anod"-ising, is that the Aluminium serves as the "anode" :

With the aluminium object serving as the anode (the positive electrode). The current releases hydrogen at the cathode (the negative electrode) and oxygen at the surface of the aluminium anode, creating a build-up of aluminium oxide.

It really should do anything the other way round?

@MegaLoMonkey Yea, I searched around more and found some more projects that other people have done. Most of the ones that i found they were using car battery acid mixed with water as their solution, which I guess you can find at auto-parts stores. Also, some just used aluminum made ''paddles''(aluminum wire wrapped with foil) as the -cathode.

But thanks for the information!

@raypsi

You can use weak solution of nitric acid to remove all impurities in aluminium.

After that you will get fine layer of clean aluminium :)

@mic363

Most important part of anodizing process is preparation.

Aluminium is a fairly reactive metal that often has a protective layer, due to oxidation with the air, so you must clean your aluminium part (first mechanically then chemically by dipping it into solution of NaOH) to remove previous Al2O3 layer.

Only then you will get some results after anodizing.

I hope you understand :)
