Anodized parts?

Does anyone know what anodising does to water cooling parts?

I want to get some barbs done, but I dont know what it will do to the water/corrsion.

Does anyone know if this will work or not?
 
Anodising is addition of an extra layer of aluminium oxide on the outside of the metal, which prtects it quite a bit. If you are running with a corrosion inhibitor (e.g ethan-1,2-diol -antifreeze) you ought to be fine. I think the extra layer of oxide makes it much more resistant to corrosion as well, but ultimately it is still aluminium under that, so it will eventually get eaten by the copper unless you do have some corrosion inhibitor. TBH as long as you don't run distilled water only, I reckon you should be reasonably safe.
 
thanks for that.. What I should have made a bit more clear is that I will be anodizing them with paint, not alu.

I want to get some black barbs, but I'm scared that the paint might break something :S

lol well thats not anodising them then! ;)

To anodise something you need sulphuric acid, pure distilled water, a power source and colour dyes etc.

I've been toying with the idea of powder coating some barbs glossy black, it might look pretty good. :D

Copy :O

If you did, I'd deffinately be interested to see if it works ok.. Could the paint not come off in the water?
 
Shouldn't do no, powder coating doesn't flake like normal paint does, it forms a kind of skin on the object.

I'll try it on some EK barbs and post up the results. :)

:) If it looks good I've got a bag of feser Barbs sitting around :P
 
You going to do some anodising yourself luigi? I made a guide quite a while back on doing it if you're interested.

I saw that, But I don't think I'm quite up to doing it myself, and my parents deffinately wouldnt let me :(
 
Got the link handy Matt?

Just bought in a load of plastic containers to have a play with, just need to try source the sulphuric now... seems harder than I initally thought. :-S
 
@ Matt

In other guides i've seen people use aluminum wire and aluminum foil to create the cathode, any real difference in doing that and using lead bar?

Also for the dyes, did you ever try textile dyes?

@Diablo

Cheers, will have a scan on their website.

I've just e-mailed Caswell as well, hopefully between the 2 i'll land something.

If my chemistry knowledge fairs me well it's something to do with the reduction and oxidation that mean you shouldn't use the same material for both anode and cathode.

Though that was a few years ago..........
 
Yeah, you don't want both anode and cathode made of aluminium, the different metals isn't as important but the reistsance will build up as you oxidise the outside of the alu...that will slow it all down a bit.

You need something that won't eat the aluminium such as copper (well too much anyway). Lead is often used cos its not going to eat the aluminium, won't dissolve and won't rust.
 
Aah that makes sense now, i'll try hunt down a lead rod, scrap yard should have something shouldn't they?

Already got a 12v Battery Charger and plenty of plastic containers... it's looking promising! :D
