- At great depths, the following conditions have the following effects on the rate of corrosion:
|Effect on Rate of Corrosion:
|Decrease, due to lower kinetic energies of interacting particles
|Decrease, as oxygen is essential for the formation of metal oxides
|Higher than the surface
|Slight increase, but little difference
- However, corrosion at great depths occurs to a much greater extent than would be expected from the above information.
- Much of the corrosion at great depths is caused by certain anaerobic bacteria that reduce sulfate to sulfide.
