An article from Popular Science about Rusting Aluminum, pretty interesting I thought.

http://www.popsci.com/popsci/h20/article/0,12543,693558,00.html

Make sure to view the video of the rusting aluminus that they provide, link here as well:

I read Grey Matter first thing whenever I get a new PopSci. Our Aluminum Oxide supply worries are over!

I wonder how long before some terrorist group tries this. It seems a simple way to get aeroplanes to fall out of the sky.

yeah but if you look in that video they scratched off the already oxidized area of the metal and applied the mercury to an unprotected area.

call me stupid or pedantic, but I thought only iron rusts, and other metals just oxidize? =d

Yeah, I discussed this with someone when they first told me of this article - it would be kind of tricky to get anything on the *outside* of the airplane. The odds of getting anything all the way through the inside to the outside is quite slim, and if this is as fast acting as I hear, if someone got something on the outside of the plane - while on the ground, as I don't see it feasible to do otherwise (by a person, anyway) - the plane would never leave the ground, as someone would surely notice a lack of structural integrity. They'd really notice if the whole wing was sitting on the ground next to the plane [Wink] .

Aluminum also "rusts" naturally. However, when our friend Al is exposed to oxygen and oxidizes, it the Aluminum Oxide forms a protective "paint" about the surface of the metal. When the metal is cut, it is unprotected, but, eventually, it will oxidize as well.

There are other metals that rust as well. Maybe even all of them It's been a few years since chemistry, so i might not be 100% correct about this.

Also, the page has been "404'd."

" In crystal form, aluminum oxide is called corundum, sapphire or ruby (depending on the color),.. "

i had no idea!

<pedantic chemist>
Actually it's the impurities in the carondum that give ruby and sapphire their color. Pure carondum is colorless.

Better call the Department of Homeland Security and tell them to lock down all stockpiles of mercury and ban thermometers and barometers...

I thought it was "carborundum", or is that just a tradename on sandpaper?

Or am I just completely wrong?

I'm not sure if langage has evolved further yet, but orignally, rust just another term for oxidized iron =__=

RUST, RUSTY--------I first heard these terms when I was a lad on my Grandma's farm, and used to discribe the condition of the cattle feed. Don't feed the cows rusty corn or silage be sure to look at all of the silage. Years later I learned about rusty Iron & Steel and other oxidized metals. There are evan references to rust in the Bible if you care to look.
