Oxidation in Metals: Mechanism & Kinetics | Corrosion | …

1. The oxide is unstable, i.e., oxide docs not form i.e., oxidation does not occur. For example, gold is free of tarnishing as gold oxide does not form. 2. Some metals form molten or volatile oxides, such as V 2 O 5 on vanadium and MoO 3 on molybdenum: or the oxygen dissolves in the metal itself, such as in titanium.
