Rust is the reddish-brown flaky coating that forms on iron and steel when exposed to moisture and oxygen. Avoiding rust is essential to maintain the integrity and longevity of metal structures, vehicles, and other iron-containing objects.
Rusting is an electrochemical process that occurs when iron atoms react with oxygen and water to form iron oxide, commonly known as rust. This process is accelerated by exposure to moisture, high temperatures, and acidic environments.
