During galvanization, metal is coated with molten zinc, which forms a layer that is resistant to rust. Additionally, a thin layer of a zinc and steel alloy is formed, which provides rust resistance even if the outer zinc... More »

Prevent steel milk pails from rusting by completely drying them after use, limiting their exposure to salt water and storing them in a dry location. If the pails are decorative and are not used to collect and transport m... More »

Rusting is a chemical reaction where iron is slowly broken down when exposed to water and air. It is categorized as an oxidation reaction; oxygen, water and iron react to form hydrated iron (III) oxide, which is known as... More »

Chrome does rust, because it is a metal that readily interacts with moisture and oxygen. Chrome is formed by electroplating a metal with the element chromium, which has greater corrosion resistance than most other metals... More »

Aluminum reacts with oxygen to form a layer of aluminum oxide on the outside of the metal, according to HowStuffWorks. This thin layer protects the underlying metal from corrosion caused by oxygen, water or other chemica... More »

Copper undergoes a process much like rusting. When exposed to air for extended periods of time, copper oxidizes in a way similar to how iron forms rust. When copper oxidizes, certain chemical reactions form a light green... More »

Zinc is used to galvanize other metals, such as iron and steel, to prevent rusting, and several metal alloys, such as brass (zinc alloyed with copper), use zinc. Zinc is also used to make zinc oxide. Another use of zinc ... More »
