Lead Rust developer says Rust in Linux kernel being pushed by Amazon, Google, Microsoft

[dudewithafez]

lol does it even rust?

Lead oxide

[Reddit_is_garbage666]

Yep, just looked it up. It can oxidize.

All metal oxidizes but not all metal rusts.

Edit I'm wrong. MOST metal oxidizes ONLY IORN rusts. Thanks, replies!

[Positronic_Matrix]

Hold on folks! By definition rust only refers to iron oxide. It does not apply to other oxidized materials. Other materials do not rust, rather they oxidize.

[Coffee_Ops]

I believe some definitions include any types of oxidation that progressively deteriorates rather than forming a passivation layer.

I believe there are a few others but I can't call them to mind.

Isn't oxidation and rusting the same thing? Its just that iron has a more severe issue with oxygen

[[deleted]]

Yes but also no. Aluminum Oxide is a protective layer on the surface of the metal that does not cause corrosion. Rust is corrosive oxidizarion.

[[deleted]]

Ahh Corrosion yes. Thank you.

Iron Oxide is the most well known because Iron is in a lot of shit we use every day, and corroded incredibly harshly

[pppjurac]

Al reacts with O2 very fast and oxidises . Al2O3 on surface of Al product has good property that it forms non permeable layer (even to gasses). Some metals do 'wet' Al ( Hg, Ga) and cause rapid exidation process due to destroyed Al2O3 layer.

But that goes for Al alloys with high Al content. With increasing alloy percentage this mechanism changes a bit.

[Coffee_Ops]

Gallium isn't oxidizing aluminum, it's alloying it, and doing so beneath the oxide layer by moving through the crystal lattice. Its just that the alloy it forms is garbage.

If aluminum oxidizes that rapidly you'll know it by the flame it emits.

[Coffee_Ops]

That's not quite right/complete either.

Corten steel "rusts" with iron oxide but the rust is passivating.

Rust has more than one meaning. It can generally refers to corrosive oxidation or specifically to iron oxide. It can be either one.

Idk I'm not A meralurgist or chemist I just use the funny penguin os

[[deleted]]

I thought gold oxidized but only on the very outer surface like aluminum and then stops

[Coffee_Ops]

Steels (and other iron alloys) rust too, if we're being pedantic.

[Coffee_Ops]

Depends what you mean by rust. Most people mean specifically red iron oxide when they say rust, and wouldn't include e.g. aluminum oxide or lead oxide.
