WebOxidation 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.
