What causes rust, oxidation, or corrosion on metals?
Rust, oxidation, or corrosion on metals can be caused by a variety of factors. These include exposure to oxygen and moisture in the air, reaction with certain chemicals, electrochemical reactions between dissimilar metals, and more.
The most common environmental factor that causes rust is moisture in the air. This can come from rain, snow, humidity, or even dew in the morning. All of these forms of water contain oxygen which can react with the metal to form oxides that lead to rusting and corrosion.
Another factor is the presence of certain chemicals such as salt or acids in the environment. The combination of these elements with moisture can cause accelerated oxidation and corrosion of metals over time.
A third element that can contribute to rust and corrosion is temperature fluctuations. Metal, like all materials, expands and contracts when heated or cooled. This can create tiny cracks in the surface of the metal where oxygen and moisture can penetrate, accelerating the oxidation process.
Finally, an electrochemical reaction between two dissimilar metals can also cause corrosion. When two different metals are put together in contact with one another, electrons from one metal will flow to the other, creating a current that causes rapid oxidation of both metals. This is why galvanization (coating a less reactive metal with a more reactive metal) is so often used for protection against corrosion and rusting.
In summary, there are many causes of rust on metals including exposure to oxygen and moisture, reaction with certain chemicals, electrochemical reactions between dissimilar metals, and temperature fluctuations. Taking the appropriate steps to protect your metal from these factors is key in preventing rust and prolonging the life of your metal components [2].
