hi /diy/, first time posting here



how do I corrode aluminium? It's not urgent but it must be significant corrosion, not only surface



I tried searching google but every link that I get from googling is how to prevent corrosion lol, closest thing I found was using HCl but I doubt that it will be enough to corrode



thanks

Buy a new car and move to the rust belt.

Wait longer.

If aluminium is exposed to very strong acid or alkaline environments outside the pH range 4 to 9, violent corrosion will occur in the form of metal pitting. Bases break down the aluminium faster than acids - for example concentrated caustic soda reacts so violently with aluminium that it can start to boil.



First hit on jewgle. Stop being a lazy, spoonfed faggot

sorry achmed I'm not helping you down an airliner.

Put mercury on it

Apply liquefied gallium to a roughed up aluminum surface, it will infiltrate the crystal structure and make the aluminum ultra brittle. 



Also, it will be super obvious if you did this, and gallium will stain everything it touches.

>corrode

You're not corroding aluminum, because the surface is already corroded. Aluminum forms a layer of aluminum oxide, i.e. alumina, on contact with air. This "protective" layer is why welding aluminum is such a bitch.

Your options for rapid weathering are basically galvanic. Dunk it in a salt brine and mechanically scrape it as best you can to tear away some of that oxide layer. Attach a DC electrical lead to it and throw in a chunk of copper to the other. The aluminum will have a very bad time.

Many keks

I once put some stained metal parts in bleach in order to remove the stain... 1 week after I removed them they turned into balls of pure rust. worth a try

muratic acid
