Corrosion protection of mild carbon steel media in ...

 · Corrosion plays a significant role in wear of mills used to grind acidic phosphate slurry at pH 2–4 in Florida fertilizer plants. Approximately half of the grinding media wear results from corrosion or oxidation dissolution of metal surfaces in grinding. Cathodic protection using impressed current was investigated to reduce the wear rate.

4 Types of Metal That Are Corrosion Resistant or Don''t Rust

 · Copper oxidizes over time to form a green patina, which actually protects the metal from further corrosion. Bronze is a mixture of copper and tin, along with small amounts of other elements, and is naturally much more resistant to corrosion than copper. Brass is an alloy of copper, zinc, and other elements, which also resists corrosion.
