Can Corrosion Occur Without Oxygen Anaerobic respiration is the type of cellular respiration that occurs without oxygen.Longwoodmf.com. Where oxygen diffusion is the controlling factor, the corrosion rate tends to increase also with rise in temperature. In acid waters (pH <4), corrosion can occur even without the presence of oxygen.National physical laboratory. corrosion which occurs when oxygen cannot penetrate a crevice and a differential aeration cell is set up. Corrosion occurs rapidly in the area with less oxygen. The potential for crevice corrosion can be reduced by: • Avoiding sharp corners and designing out stagnant areas • Use of sealants • Use welds instead of bolts or rivets

Wikipedia. This non-galvanic form of corrosion can occur when a metal is subjected to a hot atmosphere containing oxygen, sulfur, or other compounds capable of oxidizing (or assisting the oxidation of) the material concerned.

Rusting without water?. Where oxygen, iron, and water meet is most often where rust pits start to form. Without water the formula is the following: $$\ce{4Fe + 3O2 -> 2Fe2O3}$$ This reaction is very slow. More energy is needed to initiate the reaction as in the case with burning steel wool, or another means is needed to transport electrons.

Definition from corrosionpedia. Some corrosion prevention methods such as coating, painting or blanketing can be used to reduce the metal surface's exposure to oxygen in a corrosive environment. Crevice, pitting, galvanic and intergranular corrosion can all be significantly prevented by reducing the oxygen concentration.

Why does rust occur?. Without damp, no corrosion occurs, nor does it occur without oxy- gen. But oxygen and damp are present in the air. A certain level of damp is necessary for corrosion to occur. If the relative humidity of air exceeds 60%, a very thin film of damp forms on the metal surface, and this functions as an electrolyte.
