Rusting, or oxidation, is a common problem that can affect a wide range of materials, including iron, steel, and other metals. Rusting occurs when these materials come into contact with oxygen and moisture, which causes them to corrode and form a reddish-brown oxide layer. This process can significantly weaken the material, making it more susceptible to failure.
There are a number of reasons why it is important to avoid rusting. First, rusting can lead to the deterioration of materials, which can pose a safety hazard. For example, rusted metal beams in a building could collapse, causing injury or death. Second, rusting can also lead to the loss of valuable materials. For example, if a car is not properly protected from rust, it will eventually become unusable.
