WebbOxidation is the reaction of metal and oxygen. If the oxide formed is continuous and effective in separating the alloy from the atmosphere, the oxide is protective. However, if the oxide fails to act as a separator, problems with corrosion occur. Oxidation in air When an alloy is heated in air, an oxide layer forms on its surface. Webb13 maj 2024 · Instead, it’s caused by a type of bacteria that may be on the object. What is difference between rust and corrosion? Corrosion is the process by which certain materials, metals and non-metals, deteriorate as a result of oxidation. Rusting is oxidation of iron in the presence of air and moisture. Rusting occurs on surfaces of iron and its alloys.
