When zinc is exposed to air, it interacts with carbon dioxide to generate a zinc hydroxide film. This shields the metal from external air reactions, which is why zinc is used to galvanize other alloys and prevent corrosion. Pure nickel is extremely corrosion-resistant, particularly when exposed ...
