|Rusty sputtering target.|
There's something very curious about a rusty sputtering target. Sputtering is used to deposit thing layers of metal, and more often than not the reason you're doing that is to create a corrosion-resistant coating. So sputtering targets (which are where the metal being sputtered comes from) are usually found made of metals like titanium, chromium, or nickel, which are suitable for this purpose precisely because they don't rust.
